[Swftools-common] [PATCH] Refactored environment variable overrides for setup.py

[Kai Lautaportti]

Hi Matthias

Here's a patch against setup.py that unifies the environment variable
overrides in setup.py and adds some additional logic to it.

The main changes are

  - all variables prefixed with SWFTOOLS_ to avoid conflicts with
other variables
  - option to disable building of either Python module (gfx and/or SWF)

Hope you'll find it suitable for merging.

cheers,
Kai
