[physfs] Announcing PhysicsFS 1.0.2!

[Ryan C. Gordon]

This is a bugfix release. There are no API changes. This will be the 
last release from the 1.0 branch. Developers are encouraged to use 2.0.0 
unless they are too nervous. The changes over 1.0.1 are minimal and 
pretty safe if you want a small upgrade.

   Grabbing the sources from Mercurial:
     hg clone -r release-1.0.2 http://hg.icculus.org/icculus/physfs

Notable changes:
- Uses -fvisibility=hidden on gcc4 builds, to remove non-public symbols 
from the shared library. This reduces risk of namespace collision and 
makes the binary smaller.
- Cygwin, MingW32, MSYS, and other Windows fixes.
- Fixed a handful of bugs for various platforms, and in the generic 
library code.
