Fixing / Tagging the current build errors

To be able to work on new features I tried to get the test suite back to green. This includes the following changes:
* As the rubyspec changes a bit since the last green build, I tagged all new errors as fails. From my point all new fails looks like no implemented specs. But please take a shot look whether there are specs that should be working at the moment.
* There were some new files that needed to be excluded by topaz.mspec (I added a comment with the reason). Please take a look primary on the languages specs.
* rpython changes something with regexp and MAXREPEAT. Using the rpython MAXREPEAT constant instead of 65535 fixes the errors.
* flake8 complains about "E129 visually indented line with same indent as next logical line". As this rule was violated a couple of times, it looks like an explicit decision to format a little bit different (one empty line after the visual intended). Additional I excluded docs from checking (docs/conf.py violated block comments must start with "# ").
