Made FIFE compatible with CEGUI-0 while retaining compatibility with 0.7.9 and lower. To enable it pass -enable-cegui-0 to scons. Note that it is not possible to build for both cegui versions, cegui-0 will always override cegui.
Refs #832
The name of a required library will now not be convered to lowercase when calling pkg-config or trying finding a configure command for the library. This fixes finding libraries on case-sensitive system using these methods.
Removed adding the name of libraries to the LIBS variable explicitly. This should be and is being taken care of by the configuration functions. This allows passing the correct library name to pkg-config, which does not need to be the name of the actual library file.
Split the combined cegui manager into seperate ones for old CEGUI versions below 0.8.0 and for CEGUI-0, starting at 0.8.0.
The cegui python extension for fife will automatically use the cegui version that corresponds to the installed PyCEGUI.
Also Fixed the linux scons script and translated the changed to the openbds and dawin scripts.
