Feature Request. Be able to configure not drawing rectangles on autocomplete

[ainslec]

I would like a configuration option to disable the drawing of rectangles via OutlineHighlightPainter.java. I have managed to achieve this by commenting out the g.drawRect(...) statements, and would be happy to submit a pull request to make a configurable version available, so please let me know if there is a preferred configuration approach.

NOTE : Erroniously duped this issues in RSyntaxTextArea project, this issue replaces that one.

@ainslec, sorry, I haven't been giving much love to this project lately. I'll try to take a look. If you want to submit a pull request I'll take that as well.
