Adds isolated visual tests for javascript plugins (decoupled from docs). This makes it
faster and easier to test/develop js functionality not represented in unit tests, and gives us

This commit also reverts my filter commit https://github.com/twbs/bootstrap/commit/9900771aa7f1b3ddcee49aec84082104776ace70
