[physfs] Win32 build

[Brian Hook]

Checked in some minor changes.  Updated .cvsignore to ignore the 
directories created.

Added physfs_static.dsp, which defaults to building for ZIP and QPAK 
(should I default it to building for everything?).

Removed an unused "char *ptr" declaration in qpak.c that was causing 
the build to fail (had warnings-as-errors enabled).

Let me know if this borks anything up.  I'm not touching the DLL 
version of physfs.dsp, since that can be a rat's nest of grief (as a 
rule, building a 'portable' DSP file is a pain in the ass when you 
need to export/copy the final build product to a specific directory 
for the parent project).
