This gives us a bunch more flexibility. plugins no longer have the "lib"
prefix or the version suffix, they're now installed in
$fs_sharepath/QFplugins,, builds should take much less time (in general,
only one of pic or non-pic versions are build), bins and libs can have
individual CFLAGS
about the path it's handed (need to get even more paranoid, though). the
string module just has char replacement so far. Add Draw_CenterPic to
r_progs.c, but this will only last till qpic_t is supported in qc.
the load menu almost works: just need to add key handling and fix a bug in
PF_sprintf
