Fixed bugs that caused "draw_scale" and "draw_centermark" not consistent.
Fixed following bugs related to scale and centermark:
- View menu items did not always reflect correctly when loading from files.
- View menu items and the viewport did not always have the same state
(on/off)
Fix bugs that caused crashes on gps download/upload.
The problem was caused by the parser for gpsbabel debug output.
The fix should stop viking from crashing, but the progress dialog still may not
display counters accurately for some model of GPS. The fix was only tested
with Garmin GPS 12. Fixing problems for other GPS requires output of
"gpsbabel -D 9 -t -w -i garmin -f /dev/ttyUSB0 -o gpx -F /dev/null"
This fix also plugged a memory leak in the parser..
Make "Save Image" and "Save Image Directory" dialogs reusable.
The two dialogs are now more consistent with "Save" and "Save As" dialogs.
This also enables them to remember the last directory used (annoyance otherwise).
This m4 module is necessary, at least to detect that libcurl is not available.
Sort of chicken/egg problem. Looking at gettextize, it seems that the
correct solution is to copy the m4 script of optional modules in a m4 directory
ensuring they will be found everywhere.

Added cookies to google requests.
Cookies are retrieved on the first request and stored in ~/.viking/cookies.txt.
The file is recreated (if needed) everytime viking starts.
Currently only google cookies are used. Others may be added if needed.
cookie, user-agent and referer are now added to the request header.
file.c:a_get_viking_dir() was added and should be used for others to query
(and creating if not existed) location of viking directory (~/.viking).

Bacported Evan's magic scissors from DEM branch.
To use it, select a TrackWaypoint layer, click on Magic Scissors tool,
then click 2 points on the map, viking will draw the route between the
two point using data from google maps.

Use google maps search string as comment for new immediately created waypoint.
After a successful search, before any operation that moves the map area,
a waypoint can be created for the resulted location by using "New Waypoint"
from the context menu of a TrackWaypoint layer. The "New Waypoint" dialog
will then use the search string as default "Comment".

Fix intermittent problem of map redraw.
The type mismatching (gint vs guint16) in the cache removing function can
cause coords truncated which leads to pixmaps not removed from the cache,
hence they are not updated on screen.
This only happens for coords with values larger than what a 16-bit number
can hold (> 65535). This is why the problem seems intermittent.

Small touches on the look.
- Ajust field width and alignment of treeview columns.
- Bring dimension constants to the top to make them easier to be found and
changed (Until we implement something more flexible for users to change
them)

Maps layer: Improve performance for map autodownload.
Autodownload is now only triggered when there are changes in zoom scale
or view location.
Map autodownload caused poor performance because it was triggered unnecessarily
by every update event. Most of these events are caused by interactions
that do not require map downloading. Autodownload itself is among the worst
sources of triggers. Autodownload threads generate update event for each
downloaded map tile. These events in turn create other threads
which generates more events and so on. Most of these threads will die out
quickly but the performance still suffers.

Google Directions now remembers previous query (from/to entries).
The from/to dialog will now display the previous query so that users can edit

Note that this only works for one lifetime. Viking will forget the queries
once restarted.

Gpslayer: New menu items to remove all tracks and waypoints in GPS folders.
Data in Gps folders are likely short lived. Old data are often removed
before upload/download operation. The new menu items
(empty upload, empty download, empty all) are to make the task of
cleaning up the folders less painful (now that gps data are saved
and there is multiple selection is not yet implemented).

Disable temporarily prompt for saving on exit.
Except some changes made through the top window menu, "modified" status is not

ALl changes are wrapped with "ifdef VIKING_PROMPT_IF_MODIFIED" for easily

Stop autodownload from running forever on map downloading errors.
The error status from low level of map download was not passed on.
Therefore update emits (to refrsh display) are generated even when
downloading got errors and no map tile needs to be redisplayed.
This caused serious problems when "Autodownload" is turned on.
The update emits also trigger autodownload to start new download thread
which in turn generates update emit for failed downloading of the
same tiles. And on and on.
This commit allow the download error status to be passed on and limit
update emits to successful download only.
Only google module was changed to use the new method. Other modules
will follow in the next commits.

Fix bug that causes crash on viking exit.
In some situations, for examples, when there is no map file to download,

(viking is terminated or the layer is removed).

Fix "corrupted tile" problem -- was really just that incomplete tiles were being drawn & subsequently taken into memory cache. We should really add a "clear memory cache" menu item too.
