Fixed a bug in VFSDirectory that prevented absolute paths from being resolved. * Modified the VFSDirectory constructor so that it now adds the drive root as the VFS root by default, instead of the current working directory. * Added the current working directory to the VFS in Engine::preInit in addition to the default drive root. * Reverted a change to EventManager::processMouseEvent which prevents GUIChan from grabbing mouse input. The fact that GUIChan grabs all mouse input will need to be addressed once the GUI code is modularized.
