Implementation of syntax highlighting
* Keywords highlight * Simple functions highlight * Correct highlight of oneline/multiline strings and comments - There is no update of variables list (will do after doing variable management)
I think, that managing of comments and string should be ported from my changes to Python backend. It seems to handle right things like: "some text # it's not a comment". Also it starts highlighting string while you entering its contents.
If I have time, I will try to fix handling of brackets pairs that are not placing on one line (it's a common fail of DefaultHighlighter).
