[FINAL] Added support for luatrace (profiling)

Only the following files are actually used (the rest are part of the package, and are either examples, documentation, or lua code):

* 3rdparty/luatrace/c/c_hook.c
* src/aku/AKU-luaext.cpp
* src/aku/AKU-luaext.h
* xcode/libmoai/libmoai.xcodeproj/project.pbxproj
