Fixed and cleaned up CommandContext.

Browse Source 
- Removed all the inefficient removePortionOfArray stuff and replaced it by ArrayLists that accumulate content instead.
- Added new tests
- Swapped the arguments to assertEquals everywhere. First argument is "expected".
- Fixed warnings in the test case
- I put my original flag parser back and added support for putting flags anywhere. Looks and works better than that undocumented mindfuck zml put there.
