Improvements for Python syntax highlighting

[ghost]

The Python syntax highlighting uses primarily just white and the theme color for nearly everything, which makes Python code hard to read. For example, defined function calls, method calls, variables, and strings all use the same color (in my case, default blue), so it's hard to easily discern what everything is when looking through Python files. Having separate, more defined colors for those would make this perfect; Python is the only language whose Seti syntax highlighting I have trouble working with.

I work primarily in Python and I also am very disappointed with the support for Python.
