The existing implementation of a LSB first word method was incorrect,
in addition it was implemented to the BMP code, but also used in the
GIF code. Thus is should be moved to a common location.
Also added in an implementation for FXWORD_GET_MSBFIRST, since the
GIF code will need this.

Speciifically replacing what was called the "stack_", an array, with a
vector called "decompressed_". The fact that this data structure
wasn't actually a stack caused a lot of grief when refactoring.
