[Bf-committers] Patch for auto-identation in text editor

[Bart]

That's sounds good! But there are much problems with text editor:

- no way to type special characters: < > § |
- no way for: ä ö ü Ä Ö Ü ß
- a doubleclick on a word between spaces or special characters should
	select the word
- enter on numpad doesn't work
- sometimes it slows
- using find works only if you pressing the ok button; entering the
	search word and pressing just works after pressing it twice
	again
- you must click in the Textfield of search to before
	you can type a word
- May primitive syntax highlighting for Python would be great
