Fixes #40. Texas is now working.

List of fixes includes:

1. PhantomJS was using a very narrow viewport by default. This meant that we got the mobile version of their (now) responsive site, which had different elements than the ones I was looking for. We now set the viewport explicitly to be the size of my home monitor -- wide.
2. The supreme court is now checked by default. This has the fun repurcusion that we need not click it anymore or else we unclick it.
3. They now require redirects to their subpages, which we explicitly forbid previously. Now we explicitly allow it, until they get their system fixed.
4. New, improved XPath queries.
