Just release GPX-Viewer 0.3.0.

• Install application/gpx+xml  mime type for *.gpx files.
• Update recentmanager to use this mime type for recent files.
• Call update-desktop-database on install/uninstall.
• Merge the GTK3 branch into master.
• Small cleanups.
• Port to GTK3
• Port to libchamplain 0.12
• Track now has height-colors.
• Tracks are clickable. clicking on atrack will highlight that point in the graph.
• Use GtkApplication instead of Unique.
• Stopped detection on tracks. (points detected as stopped are highlighted red.)
• Filter out points that are a linear continuation. (should make for less complex tracks, so improved performance)
• etc..
