#5 Editor improvements

[Rene Aguirre]

As a debugger I think HAP it's just amazing!.
But the editor seems to need some polishing, Scintilla it's
just great. Just consider this features:
* Allow Split Windows for text editing.
* CTAGS support for better code navigation.
* Capture the output (stdout, stderr) of programs, like
in SciTE, allow to 'jump directly' to reported error.
* Code completition.
* Better Python help file integration (at F1 jump to
keyword in helpfile).
* Allow to add other help files (imagine wxPython help
file integration).
* Easier tools configuration interface. Now it's very hard
to setup any tool.
