Git master updated

[optigon]

Optigon, just to inform, there are still some warnings in master branch:

Code:

/wings/PLUGIN~1/PRIMIT~1/wpc_cylinder.erl:200: Warning: function get_pref/2 is unused

/wings/PLUGIN~1/commands/wpc_numeric_camera.erl:87: Warning: variable 'Az0' is unused
/wings/PLUGIN~1/commands/wpc_numeric_camera.erl:87: Warning: variable 'El0' is unused

Thanks!
Added rj/fixes branch to solve the compiling errors.

The pu branch will not be merged directly with the master at this point.
The branches from the pu will have to be rebased individually before they can be added to the master.

Nice work on all the bug fixes
