Closes #1249

Patch by Alexander Gall. Thanks.

This needs to be *reviewed*.

(bug reported by David Thiel)

 - Removed the gross SUPPRESSED hack
 - Remove support for strict deprecated aliases (that was not used anyway)

Note that shortcuts are inherited from the main module to submodules, so it is
totally useless to duplicate them paste add_submodule. If you think this is
wrong, I do not necessarily disagree, but it would need a RFC.

- remove apparently harmful "continue" with an always true condition

By the way, I am VERY suspicious about the use of libvlc_global for mosaic and
bridge locks

Use SVN history if you ever want to revive it.
