Track Properties Dialog no longer blocks interaction of the main window.
- Before this change, bringing up a track dialog would stop users from
doing anything else with viking. The restriction is mow removed.
- The dialog is no longer in modal mode.
- Multiple dialogs for different tracks can be up at the same time.
- Users can only start one dialog for each track. Once its dialog is on,
its "Properties" menu item will be disabled.
- When a track is deleted, its dialog (if on) will also be destroyed.

Interpolating DEM data.
- DEM data can now be interpolated using ione of 3 methods:
o no_interpolation: Take the nearest south-west data.
o simple_interpolation: Interpolated using a simple method.
o best_interpolation: Interpolated using Shepard method.
- "Apply DEM data" for a track now uses "best_interpolation".
- Elevation-distance graph now uses "best_interpolation".
- Elevation information displayed on status bar now uses most suitable
interpolation methods according to the current zoom level.
Not much testing has been made to justify performance/accuracy trade-off
of the interpolating methods.

Added new fields to trackpoints for data from GPS in realtime mode.
- Speed, course, fix mode and number of satellites are now stored in trackpoint

- There should be no backward compatibility problem. FIles saved by earlier
version of viking can still be used.
- New data from files saved by viking from this change onward won't be
recognised by earlier version of viking and will generate (lots of) warnings
when read.

Disable half-drawn update mode when the center is moved.

Fix a long lasting bug that causes track property not working properly.
Elevation graph did not work properly for tracks that start with trackpoints
without altitude values followed by trackpoints that do have alt. This
can also cause segfault in some case (more track points without than ones
with)

Downloading maps from gogle requires a number embeded in the request uri.
These numbers are known to be changed by google over time.
Viking now tries to work out the current numbers instead of using the hardcoded.
This is done once right before the first google map download request, in a
viking session.
So it is possible to build viking on system not offering such feature.
By this way, viking will only fail on system without $HOME, nor functional
g_get_home_dir, nor mkdtemp function.
- Use g_build_filename to concat path elements
- Use g_get_home_dir as fallback
Glib offers a function to retrieve the home directory of the current user.
As it is not based on $HOME, we use it as a fallback function.
See http://library.gnome.org/devel/glib/stable/glib-Miscellaneous-Utility-Functions.html#g-get-home-dir
Fix a bug that causes crashes when using "Maps Download" tool.
The crash can be reproduced consistently using the followings:
1. start viking without argument
2. create a map layer, using default settings.
3. select the map layer.
4. select "Maps Download" tool on toolbar.
5. click anywhere on the map (the viewport)
This problem was due to the mode of the center coord was not initialised.
THe problem is now fixed.
Make viking's default start location somewhere more likely has maps.
The location before this fix was virtually nowhere in the sea which
has no maps from most popular sources. This can be quite confusing
for first time users who don't even know how to navigate to a location
that has maps.
Viking now starts in New York City. Not because it is my most favourite
place on earth (which is Sydney BTW), but it is because we more likely
find maps there.
Refactoring: retrieve the VikWindow from the VikViewport via its GtkWidget nature
Instead of storing one more reference in the VikVewport structure,
we use the fact that VikWindow is the top level window. So, it is possible
to retrieve it from any of its children. And, hopefully, VikViewport
is also a GtkWidget, child of the main window.

A new menu entry allows to upload the data of a TrwLayer to OpenStreetMap
as a GPX data file.
Technics:
The button opens a dialog to request the needed parameters:
- authentification informations (email and password)
- a filename (initially built with the name of the TrwLayer)
- the descriptios, tags and visibility of the trace
Then, a background thread is activated.
TODO:
- Check the parameter (not empty, syntactically correct tags)
- Error handling: as the upload is threaded, the error is not displayed
- Allow to upload a simple track (not a whole TrwLayer)
It is no more a optional feature, but an "hard" requirement.
The main reason is that it is time consuming to maintain code
to work with and without libcurl. Furthermore, libcurl is available
in a lot of distributions now.
