The libogc limits the MUTEX up to a count of 64.
Therefore we use "only one" global Mutex for all Elements.
This has to follow tath a lock hinder each thread
tath which tries access to any other element
Also the new Lock-Stuff uses one global mutex.
But this mutex is locked for the smallest time as
possible (Only in the lock- and unlock-process).
The threads are no longer hindered unnecessarily each other.
This speeds up the gui
