Ran PEP8 and use os.path.splitext to detect language

Ran PEP8 to make everything look pretty.

Changed from explicitly replacing the .tmLanguage extension to using os.path.splitext to get the filename without the extension so that it works with the new sublime-syntax files.

Replaced `from xml.dom.minidom import *` with `from xml.dom.minidom import parseString`, since that's the only function used from that module.
