browser tests should cleanup after themselves

[boneskull]

Currently we have to build Mocha (I think) to use it with karma-mocha. But after the tests are complete, we tend to have a modified mocha.js.

Solution: modify the clean target to git checkout -f -- mocha.js instead of rm -f mocha.js.

I hope that works in Windows.

That git command seems to work fine on Windows as far as I can tell.

This was a neat idea, but apparently at some point we opted for the BUILDTMP folder instead, perhaps to ensure that if the cleanup were missed due to failing tests everything would remain OK (and we could then look at the BUILDTMP file from the failed tests if needed for investigation). Feel free to reopen if this issue is still needed for any reason.
