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.

Example script that can be used to upload a track as a route to a predefined GPS device.
This can be used inconjunction with the export GPX with external program to upload a route to the GPS in absence of true GPX route support in Viking at present.

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.

Fix potential GdkPixbuf-CRITICAL warning in thumbnail creation.
This can be generated when trying to open non existant image files (e.g. if stored in a .vik file)
Error was introduced by commit 6d0927b1b61b1f2f9ec5d048d85d8a4cad24f649, which uses a variable without testing if it is valid.

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.
Also shorten name as preferences is already in the dialog title.
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.

Add control of GPS upload/download of components tracks and waypoints.
Controls added for both GPS Layer and acquire methods which alters the command used to run GPSbabel.
Thus the user can decide if they want to just get waypoints for example.
The defaults are set to do everything (just as previously without the individual controls).
