[Checkins] SVN: zc.selenium/trunk/src/zc/selenium/selenium.py Added the ability to run coverage tests over all selenium tests.

[Stephan Richter]

Log message for revision 87133:
  Added the ability to run coverage tests over all selenium tests. 
  Unfortunately, we need to use a different server in this case, because 
  ZServer uses the thread module, which ignores the trace that the 
  coverage tracer installs. It works well, but it is slow.
