New argument parsing library supporting multiple passes, case sensitive and insensitive arguments, default handlers and other features that were hacked in the previous ugly switch system. Very simpler system for adding new arguments, easier to see conflicts and no more replication between BG and non BG mode arguments.

I've tested pretty much everything except GE options (-g options), but some small bugs could have sneaked in.
