(includes plugins & resources).
Still need to copy frameworks before deployment.
FindOGRE.cmake finds Ogre plugins dir on OS X.
Default OS X data path set to the data subdir
near .app.
README_Mac updated.
Details:
- create a sub directory to store CMake scripts (later more to come)
- add a search Ogre package script (may be replaced later by "official" Ogre 1.7 search script, since they switched to CMake, yeah !)
- fixed header issues being not available with MSVC and replaced by equivalent functions if assumed portable enough
