Styling in the wxPython2424 demo, a patch

Hi Neil, hi Robin
It's me again! Jean-Michel

win9se, Py 2.3.0, wxPy 2.4.2.4 (non Unicode)

I have two good news and a bad news.

Good news #1
I create a small app using stc. It uses proportional bold fonts. Caret is moving ok.

Good news #2
I made some more tests with my patch application, putting all styles Arial, Verdana, ..,
bold. Everything is working fine.

The bad news (but not dramatic)
The wxStyledTextCtrl_2.py from the demo is really broken. I do not find *exactly*
what is causing the effect I discussed in my previous post. I suspect the missing of
default values before the StyleClearAll() call !?

Read my previous post, too. It has other infos.
