Description:
Implementation of GifDecoder that is more memory efficient to animate for 
Android devices. This implementation does not house in memory a Bitmap for 
every image frame. Images are instead decoded on-the-fly, and only the minimum 
data to create the next frame in the sequence is kept. The implementation has 
also been adapted to reduce memory allocations in the decoding process to 
reduce time to render each frame.

Local Modifications:
Broke headers and frames out into separate files and added ability to share
headers between multiple decoders. Added interface for reusing bitmaps each
frame. Bugfixes.
