renaming jqUnit

[Justin]

Hello,

I'm nearing the completion of switching from jqUnit to qUnit.

In brief what has happened is that latest version of testrunner.js and  
testsuite.css have been downloaded and will replace what we have in  
the repository.

This means some minor changes to jqUnit which should be largely  
unnoticed as they are wrapped in functions.

The bigger difference is that qUnit exposes several assertion  
functions to the global namespace (i.e. ok, test, stop, start, and  
etc.) Previously we had aliased those in the jqUnit namespace. This  
will no longer be done. That leaves the custom assertions and the  
jsUnit compatibility assertions as the only ones using a namespace.

With that being said, the jqUnit name doesn't really seem to apply  
anymore and could probably be changed.

Here are a few possibilities:

- xUnit
- flu

Since I need the name change in order to complete the conversion,  
please post your suggestions by the end of the day.

Thanks
Justin
