Assistant: Make Result bitmaps virtual/lazy

Browse source 
Result classes now return their bitmap via a virtual Gfx::Bitmap*
getter. This effectively makes bitmap fetching lazier, since only
results that end up on screen actually get asked for their bitmap.

This drastically reduces the amount of work done by the FileProvider
background worker.
