[WIP] Fix broken components

[jezze]

This is heavy Work In Progress and only to request for comments. To begin with, I need to seperate this commit into seperate commits. Anyhow.... these changes include:

• ncurses: could not compile on a newer gcc-5.x so ncurses was updated from 5.9 to 6.0. This ment the patch did not apply so I just removed that. Probably a bad idea.
• dialog: needed to be upgraded because of the new ncurses version
• libopk: A previous patch ( 99d6e4f) added bindings/python instead of just python to a cd. This did not work for me so I had to revert that change.
• mesa32-etna: __progname was undefined so it broke. I created a patch that removed uclibc from being handled the same as the BSDs. I don't know if this is the way to do it but it worked.

Ok, let me know your thoughts.

Ok, one more comment. The libopk problem happens because the version used in opendingux-2014.08 is 1.0.6 but the bindings/ directory appeared in a later version. Changing LIBOPK_VERSION = master is another possible way to fix the problem.
