[Urwid] Colored border class question

[Joern Koerner]

Hi everyone!

Based on some posts to this list I've created a Border class, that draws ba border with title around widgets. So far so good. 

My problem is, when I tray to change the borders color,  only the top line and the bottom line are being ignored. They simply does not change the color and I can 
not figure out where the bug is....
Perhaps someone could give me a hint what is wrong?!

Best,
 Joern
