 get_theme_mod() calls get_current_theme() which in turn calls
 get_themes().  get_themes() scans and parses all themes.  This means that
 themes that call get_theme_mod() scan and parse all themes on every page
 load.  This includes themes that use the custom image header library.
 Profiling on my testbed revealed that 10% of the load time for the front
 page was due to get_theme_mod() and friends.  Saving the current theme in
 options eliminates the need to rescan themes on every load.
