LibCards/CardPainter: Add a helper for accessing the caches

Browse source 
The CardPainter in LibCards caches already painted bitmaps. This adds a
helper that gets the bitmap from a cache or creates a new one, if the it
doesn't exist yet. It does this by calling a creator function with the
new bitmap, which can then paint into the bitmap. This makes the code a
bit simpler and shorter.
