Speed up start times of applications:

	-Do not load MimeType when using Resource::loadIconSet
	 we introduce a global boolean (like TT)
	What is bad: The boolean is visible outside of libqpe and
	we've that extern in the header...
	On the former we can use visibility attributes soon

   The allSounds() function returns a list of all the sounds available.
   A particular sound can be searched for using findSound().
 
   Images can be loaded with loadImage(), loadPixmap(), loadBitmap()
