sublime-syntax version of Python Improved

[MattDMo]

.sublime-syntax files are a huge improvement over .tmLanguage ones, although AAAPackageDev has made editing them much easier. Unfortunately, only the dev builds support the format at the moment. However, at some point the next public beta will be released with support for the new format. In the meantime, it wouldn't be a bad idea to use the dev build's convert to sublime-syntax functionality to convert PythonImproved.tmLanguage to PythonImproved.sublime-syntax, push it to a new branch in this repo, and start hacking on it.

Once 2.1 is released, I'll convert it and start a sublime-syntax branch, then post back here. Any help you could provide would be ... helpful 😄
