* Split game module into game and game_interface
* Move core_lib to corelib
* Move miniwindow to corelib
* Introduce init.lua script for initializing the client, giving much more flexibility
* OTClient is no longer Application derived and is much simpler
* Fix recursive reference memory leak in UIWidget
* Make Event/ScheduledEvent memory-leak safe
* Fix exit crashs by freeing graphics resources before destroying GL context
* Add many asserts to avoid any leak regression
* A lot of changes in lua binder to compile with clang's libc++
* Add more portability to luabinder
* Remove const keyword from bound lua functions
* Deprecate std::bind usage with luabinder replace its usage with registerSingletonClass/bindSingletonFunction for binding singleton classes
* Fix a bug in lua binder where calling functions with bil object would make the client crash
* More fixes to compile with clang
* Add cotire cmake module to speedup compilation https://github.com/sakra/cotire
* Fix clang error and warnings
* Rename Font to BitmapFont to fix conflict with Xlib.g Font typedef
* Remove legacy PCH support
* Improve Position hash
* the rendering now consits of two panes
- the background pane (for animated stuff like the map)
- the foreground pane (for steady stuff, like UI)
each pane has it own max FPS and works idependently
this may increase graphics performance on many platforms
* use shared_ptr for InputMessage and OutputMessage and bind them
* allow sending network messages from lua
* implement extended opcode
* use own OS type for otclient to allow server side detection
* fixes in input event bot protection
* move RSA to input/output network messages
* allow to capture opcodes before GameProtocol parsing with the event GameProtocol.onOpcode
* fixes in lua std::string pop/push to allow byte buffering
* option to pass -opengl1 or -opengl2 as argument
* note that with this commit there are a lot of graphics regressions and the master will remaing unstable for a while
* shaders disabled for a while
