Make the track name a property of the track.
This is important step in being able to support undo operations.
This also gives the ability to have multiple same named tracks.
ATM maintain usage of a hash table for the list of tracks, but instead of using the (forced unique) name for the hash,
use a simple integer as a kind of UUID.

Add CalTopo 7.5" (24k) USGS Topos!
msrmaps is going away, add these just in time!
I contacted them about using their tiles. I'm a bit unclear on the license (if there is one?), because it isn't displayed on their home page, but what I mentioned what I wanted to do with them (use them to make my own custom topos for free redistribution) he said that was OK:
"Because the underlying data is public domain I don't know if I could actually prevent someone from reassembling the tiles into a map, but I wouldn't want to even if I could. By all means feel free to do what you're describing."
When I asked about using the tiles in Viking, he basically said go ahead: "You guys should go ahead and use the tiles, and if bandwidth becomes a concern we can sort it out then."
Many extensions can be added through a simple configuration file.
Currently, only user's home directory is used to load such configuration.
This patch add support for some standard locations in system.
The behavior can be affected by XDG_DATA_HOME and XDG_DATA_DIRS standard
environment variables.
Viking uses g_debug function. But in glib 2.32, the g_debug behavior changed and all
DEBUG messages are discarded, unless G_MESSAGES_DEBUG is set. So, "viking -d"
no more work as its design was to mute DEBUG messages when "-d" is not set.
Now, printing is restored via a dedicated function.

Fix Track Properties graph blob marker drawn at wrong elevation when elevation graphs have different min/max heights.
Use separate values for each elevation graph minimum values and indexing.
Normally these values are the same but sometimes they differ due to differing methods of altitude array creation.

Add function to return an average moving speed for a track.
This method doesn't use samples that differ over the specified time limit - effectively skipping that time chunk from the total time - hence removing the 'stationary' bits to give only the moving parts.

Add ability to open a TrackWaypoint layer with an external program (default JOSM).
This is ideal for editing around the track and waypoints with OSM, as it's very unlikely Viking will ever be an OSM editor - it's best left to other dedicated programs.
The layer is converted to a temporary GPX file, but it is not deleted as loading it with another program is not instantaneous.
For now it is up to the user to delete it / use system temp cleanup methods.
The program can be changed by the user and is stored in the preferences.
This *hasn't* been tested on Windows OSs. It's possible a full path to the program may be needed to invoke it on such systems.

Add ability to geotag images interpolating times against tracks.
Geotag information is saved (when specified) as EXIF GPS information using the built in libjpeg component of libexif. (EXIF writing using libexif is more complicated than one would wish!)
The geotagging can be invoked 3 ways:
. Directly updating an image that is already on a waypoint
. For specified images on a TrackWaypoint layer (all tracks with the layer may be used interpolating a match)
. For specified images on a specified Track
Various options are given to the user to control the geotagging process:
. Whether to write EXIF
. Whether to create Waypoints from the images.
. Whether to Overwrite existing GPS information
. Timestamp issues:
- Whether to change file modification time
- Time offset between creator (normally the camera time) and actual GPS UTC time
- Cater for time zone setting of the creator (again normally the camera setting)
Much of this work has been inspired by GPSCorrelate. (http://freefoote.dview.net/linux_gpscorr.html)

Enable internationalization and simpilify 'Global' preferences text into less specific 'General' term.

General is a better term, as all preferences are 'global' when considered from an end user point of view.
This enables further 'global' tabs to be named according to some logical grouping (even if is just 'Advanced').
Issue derives from commit: 6e4a49aa9ec3ca64334124a009d4774a7bb4bb8e back in early 2008, which replaced GtkFileSelection by GtkFileChooser, this changes the signal callback from using an array of strings (gchar**) to being a GSList type.
