New CTSim v5.1.0 in Sid

[Kevin Rosenberg <kevin@rosenberg.net>]

I received many requests to port CTSim to a version of wxWidget newer  
than 2.4.

Trying to satisfy such requests, I've finished porting CTSim to  
wxWidgets 2.8.
CTSim 5.1.0 is the latest version.

To the degree that people are interested in this software, please  
consider testing
5.1.0 and let me know if you find any problems.
