Usable version

First pass of what I'd call "usable" versions of the pages:
- Index
- About
- Tickets

There's some more work to be done in the year_con partial to represent each of the conference years.

The biggest change of this commit by far is the introduction/commonization of the partial 'features.html'. This is the behemoth of a partial that effectively gives us the options to show slide style content. At some point it might be advantageous to break it apart more, but it's relatively straightforward to include in a layout and start putting together pages.
