* fixed a couple of remaining issues with vector icons,

Browse Source 
there is some unfortunate code duplication in AppFileInfo,
  because it cannot use BMimeType/BNode alone to retrieve icons,
  now it works closer to the code in BIconUtils, this fixes
  R5 icons not displaying for other icon sizes
* implemented a bilinear scaling function, I don't know if
  it is very fast, but I hope it is reasonable. Now that I
  see the results though, I wonder if R5 icons should be
  scaled with nearest neighbor instead...
* corrected a small bug in the icon format stuff...
  7 bit coords are -32-+95, not 96
* improved comment for BIconUtils function
