Fix style issues pointed out in code review. Move acquireWakeLock method into
MyTracksUtils and call that from ImportAllTracks and ExportAllTracks. Replace
important Toast messages with dialogs.
ImportAllTracks is essentially just a modification of ExportAllTracks that
uses the existing GpxImporter to import all GPX files found in
/sdcard/MyTracks/gpx. So that the import functionality can always be accessed,
the MyTracks Activity's MenuManager is altered so that the Tracks button shows
regardless of whether there are any tracks in the database (ImportAllTracks is
launched by a button in the lower right of the MyTracksList activity).
A Toast message shows if no GPX files are found; this serves as a hint to
users on where to put GPX files for import so that this addition should be
discoverable and useable without documentation.
