Added jshintrc, some file-specific jshint options
Basic websocket exchange working
Re-implemented underscore qunit tests in jasmine

These tests are based on the underscore project's original tests, but strips
away some of the more advanced stuff like contexts. Some cleaning up is still

The official underscore library makes all these tests pass.

This could certainly use a bit more editing--perhaps make the stack trace
collapsible and add in the offending test's body--but it's a decent start for
our purposes
Added iframe containers for tests
General restructuring, added autorefresh for tests
Increased size of test area
