config: added option parsing and config.parse()

* import config.py now does not cause any action
* config.parse() starts the process (invoked from koublad.py's main function)
man: delete old man pages (forgot to remove them)
make: add .pyc file removal to make clean target
just a reminder for tomorrow!
Merge pull request #2 from sduchesneau/master
