SC-Events

Created SC events scraper.

I'm not quite certain if I did this right. Here's an example event.

The agenda pages, if available, have the info related to the bill and participants. Yet, the format isn't exactly parse friendly. Most of the pages look like a memo. The participants, if available, are in random places. The agenda pages are more for human consumption.
