add ability to search by testname

[jmaher]

it would be great to search by test name as well, 2 ways:

1. url param: &testname=tp5o
2. drop down selection in the search field- this wouuld be a static div at the top of the page with the current test selected and when a new one is selected we would reload the page with the new filtered tests.

this should work in conjunction with other parameters:
&rev=xyz&platform=linux64&testname=tp5o
