converted the tmLanguage file to a json-tmLanguage file using the "PLIST to JSON" sublime text plugin to improve readability
added comments so the various quoted sections are easier to read; did not move sections around to make it easier to diff against the vanilla syntax highlight definition
added python 3 byte string definitions; some fixes to unicode string definition comments; allow normal strings to have unicode escape sequences too (in python 3 they are unicode strings)
built PythonImproved.tmLanguage
