testing something for input issues
Fixed some more compilation errors on Linux/Mac when compiling as a Debug build.
Fix compiling on linux
Fixed player locked on map start

In SP, when a map finished with a locked player (e.g. t1_rail) the
player is also locked (can't be moved) on the next map. The lock state
is also saved in the save game, so reloading the map does not fix it.
Fix some compiler warnings
Merge remote-tracking branch 'upstream/master'
Updated CMakeLists.txt files to use a minimum of 2.8.8.
Merge branch 'master' of github.com:xycaleth/OpenJK
Revert 44b5918c8274f166347dd5ebe8c046ca8d193f9e.
It causes a potential inconsistency with loading game .so files from places it probably shouldn't.
Fixed compiler errors in rd-vanilla SP project.
Fixed rd-vanilla SP project for FinalBuild build configuration (I swear I
fixed it last time!)
Fixed #282 - SP and MP now use libpng instead of relying on hand-rolled
implementations. Also moved common dependencies into the lib/ folder. As a
result, had to tweak a lot of files!
Fixed SP project files for moved dependencies.
Unused variable in SV_ConSay_f
Remove old/wrong license header from sys_loadlib.h.
Will be replaced in a coming commit with correct global license.
Merge remote-tracking branch 'TheRikke/master'

Conflicts:
	code/zlib32/deflate.cpp
Use correct enums for precision timer case statements in sv_game.cpp.
The values are still the same, no compat problems.
TRAP_STRNCPY was not 64-bit friendly (never used but still would possibly complain)
Many instances of using int instead of intptr with JKA specific code with VM_ArgPtr.
Batch of 64-bit fixes.  Removes _M_IX86 from being hardcoded in cmake as well.
