* 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
* fix black cursor on win32
* fix front buffer refresh on some x11 platforms
* fix outfit framebuffer glitch
* display entergame by default
* change some icons
* partially restore vip, battle, healthbar, skills and inventory modules
* more fixes on UIWidgets
* implement UIMiniWindow close/minimize functionality
* allow drag and drop miniwindows beteween game panels
* implement draw clipping using opengl stencil buffers
* allow to create Widgets by style name with g_ui.createWidgetByStyle
* styles can now have children widgets
* make proper use of the isNotPathable in pathfinding
* add scrollbar skin
* save log messages to otclient.txt
* fixes in FrameBuffer and HardwareBuffer to work with OpenGLES
* possibility to get compilation information from lua (compiler version, build date, build revision, build type)
* make crash handler more informatave
* handle assert crash signals (SIGABRT)
* zooming without real FBOs kinda works, but with lower quality
* hardware detection for glGenerateMipmaps
* possibility to disable bilinear filtering, mipmaps, framebuffers, and realtime mipmap generation in g_graphics
* otclient works well using 3D acceleration in VirtualBox again
* many fixes regarding FBOs fallback implementation
* use OpenGL 2.0 auxiliary buffers when FBO is not supported, thus this means that OpenGL 3 is not a requirement anymore, so otclient might work in older video cards
* map zooming will never work well with Opengl 2.0 because of glCopyTexSubImage2D limitation
