Remove test program with lua errors

Special case that causes false test failures due to lua outputting line numbers.
Too much effort to resolve and this case is probably not needed anyways as it
is unlikely our obfuscator would change/suppress lua error messages of broken programs
if it is tests pass for working programs
Fixed #6
Organize tests by test cases of obfuscation levels

Tests are batched by obfuscation levels to give a sense of progression
(or regression) as we test further obfuscation levels.

Future obfuscations levels can now be added by changing an int.
Mark Level 0 obfuscation testing as complete.

Added several more programs. Should really have more (close to 20-25)
but level 0 seems fairly stable and without issues. If there are bugs,
should be easy to detect as we continue testing progression.

Move focus to level 1 obfuscation testing now.

Completed #3
Test Harness: Minor cleanups and add some comments
Pull PKU obfuscator updates
Clean up obfuscator before integration

Should be a drop-in replacement to the previous obfuscation method.
Need to link the 2 algorithms with obfuscation levels though we
might want to rethink labeling obfuscation by name rather than
level as they are just different ways to replace variable names
without any "level" or gain in obfuscation between them. Also it
doesn't make sense to use both algorithms; MLA last will discard
any changes by Exchange. Exchange last is pretty much useless on
minimum strings.
