Rename *MIN_SCRAMBLE_LENGTH variables and check that they actually work

[jfly]

See https://github.com/cubing/tnoodle/issues/156#issuecomment-31508133 for renaming the variables, and https://github.com/cubing/tnoodle/issues/156#issuecomment-31574059 for checking that pyraminx and 222 are always solvable in exactly God's number turns.

@ChenShuang, do you think you can take this issue on when you've got some free time? There's no immediate rush here, but it's definitely something that should be done eventually.

OK. I'll check the assumption in about 2 weeks. BTW, the solution of pyraminx does not include tips, which means that the length might larger than "MIN_SCRAMBLE_LENGTH" or "EXACT_SCRAMBLE_LENGTH".

Wait, then how do we filter Pyraminx?

The length includes tips. The filtering is correct.

I believe Chen Shuang is referring to the SCRAMBLE_LENGTH_INCLUDES_TIPS boolean in PyraminxPuzzle.java. I vaguely remember us having to deal with this.
