added q3map2.exe install to the core directory (Q3 Executable files in setup)
bumped to version 4 project files:
- this will cause a project reload on existing installs running version 3 currently
- adds __APPPATH expansion to g_strAppPath

Q3's new quakev3.qe4 (the v3 in the name is outdated now, but not gonna change
this) has correct version and __APPPATH + q3map2 commands

All other quakev3.qe4 need to be updated. RTCW-JKII-SOF2 etc.
And check the setup (nightly) installs the new .qe4 also
