Style: Restylized entire codebase

Restylized entire codebase to deal with inconsistencies.
This was done with an automated run of uncrustify, so there may be some odd
formatting for now.
The guidelines for formatting are in place at the sourceforge website and all
known changes appear to fully match them.
