[PyKDE] Small autoindent feature for eric-3.0.1

[Torsten Marek]

Back in the days when QScintilla was really new, I wrote a little widget to test out its features, and I also added a small autoindentation which goes somewhat beyond autoIndent(bool), because it unindents on return or pass resp. two blank lines. It's more a poc, but nice, though, so I added it to the eric3 Editor widget.
There are some configuration features I miss about eric3, like setting the font for the pyshell or for brace highlighting, but I did not want to mess up the configuration dialogs (and I was to lazy, too), so I wrote no patch for that. Keep on hacking, eric3 is really great.
