Fixed a couple case sensitivity bugs and added an example

Bugs fixed:
- Case-sensitive parsing was completely broken, this has been fixed
- <Ctrl>+D to quit wasn't working when case-sensitive parsing was enabled, this is fixed

Added a "case_sensitive.py" example in the examples directory for quickly testing case-sensitive command parsing behavior.
