Added workaround for bugs with CMake 2.x FindFreetype package, uses an included version from 3.0 now if running on earlier versions.  If running on CMake 3.0 or newer, no override is done to ensure the latest version is used
Moved our custom FindLua.cmake into v2fixes directory and only use this version when not using CMake 3 or later, when using later versions of CMake the built in FindLua is used to ensure we're always using the latest version
Minor tweak to make locating the PackageHandleStandardArgs module more resilient and natural
Fixed bad include path for v2-fixes modules
Merge pull request #201 from libRocket/feature/cmake-v2-fixes
