[doc] Remove a now invalid statement: GitHub is our master now
[robots] Make robot (core) name matches builder name

Basically, it means remove the hideous Class at the end of their class
name. A few component has been renamed to match properly the builder
name.

While here:
	- remove some logger.setLevel(logging.DEBUG)
	- add missing argument in Victim::heal

Fix #321
[bin/morse] Restore the possibility to run a 'blend' file
[bin/morse] Do not create anymore scene.XXX.blend

While here,
	- simplify some part of the code
	- remove dead-code (no {script,blend} file in particular)
	- remove create_copy_default_scene which is not useful anymore (it
	  was the one which creates tons of *.blend file).

Fix #323.
[bin/morse] Pass -y (--auto-exec) to blender

Previously, it is the default, but it looks like it will be disabled by
default for 2.68 (current version). So pass it explicitly.

Must not change the behaviour on previous blender version.
