Fixed a few bugs and examples

Bug fixes:
- case_insensitive is no longer a runtime-settable parameter, but it was still listed as such
- Fixed a recursive loop bug when abbreviated commands are enabled and it could get stuck in the editor forever
    - Added additional command abbreviations to the "exclude from history" list
- Fixed argparse_example.py and pirate.py examples

Other changes:
- Organized all attributes used to configure the ParserManager into a single location
- Set the default value of "abbrev" to False (which controls whether or not abbreviated commands are allowed)
    - With good tab-completion of command names, using abbreviated commands isn't a particularly useful feature
    - And it can create problems
