UIUC Create This! Day 2013-03-28

Our changes to the front end web project. I tried to manually merge things to keep UIUC specific stuff out of it. Major changes include:

- Way for the front end to accept org_filters to pass extra information to the backend.
- jQuery has deprecated attr("checked"), so switched it to prop("checked").
- Add an "Open at Any Time" option to the filters.
- Use HTTPS to fetch external resources, so that the web frontend will work under HTTP or HTTPS.
- Our accessibility guy informs me that "<label><input> Text</label>" doesn't work properly in all page reading software. We've switched it to "<input><label for>Text</label>".
- Use fieldsets for easier navigation in page reading software.
- For located spots, nest the OL of spots under the LI for the building. This makes it a more logical grouping for page readers.
- For located spots, move the type and capacity information under the name and location description. This is so that page readers get the most important information first.
- When opening spot details, set a default focus.
- Other minor bug fixes.
