Release of cleven 2.5-1 in extras-devel

This should provide the support for the KP50 and give some time for freemangordon to find a better solution for platform support of the new drivers (without people distracting him).

To casual users: Please allow people with more experience to test it first before you upgrade. I have not tested it with all Power Kernel versions available.

Changes:
NEW: Added support for KP50.
NEW: Include binaries of version 0.2 of the bleeding edge wireless drivers.
CHANGE: Moved load.sh and unload.sh scripts to main folder.
CHANGE: Modified load.sh to accept options for the driver selection.
CHANGE: Updated the sudoers file for the new location of the load/unload scripts.
