""" Base script editor class for KnobScripter.

The KSScriptEditor is a QPlainTextEdit adapted for scripting: it provides a line number area,
and extended functionality for duplicating or moving lines.
Wouter Gilsing built an incredibly useful python script editor for his Hotbox Manager (v1.5).
Credit to him: http://www.woutergilsing.com/
Starting from his code, I changed the style and added extra functionality.
