Theme related fixes:
Browse files Browse the repository at this point in the history 
 - implemented 'fall back' support so that if a theme is missing icons, the default theme icons will be used instead.
 - use a static function in qgisapp to get theme icons and pixmaps
 - updated all icon fetching code to use the new methods above
 - updated qgsapplication so that it differentiates between active and default themes
 - fixed a bug in qgsoptions that prevented themes being changed in some cases.
This is a part fix for #1054 - still need to do some work to make GRASS theming work properly
