Spoike 8197e0875f Track areas properly, so we don't bug out when a client has multiple cameras in different areas. 
Fix up r_ignoreentpvs 0 to check areas properly.
checkpvs builtin can no longer mess up area checks elsewhere.
Write out foo.db files for release builds, in the hopes of at least getting function names from release-build crashes.
Implement _skyroom worldspawn field, still needs a few tweaks though.
Try to fix android surface-related crashes, AGAIN.
Separate parsing of connect requests, in preparation for formal logins (and removal of the old ranking code).
A few tweaks to try to improve compatibility with q3 mods.
