Reorganizing files, adding tournament calendar.

Move the tournamnets.php file to it's own directory, so it'll be easier to
add the calendar, create, compare, and search pages just for tournaments.
Also added a CSS file again. This time I'm gonna keep it, because I need
that particular selector to get the calendar to display correctly.
As always, there's something I need to do to get GAE to work.
Well, maybe this will work.
Aha! Here we go.
Adding in routing, and more tournament stuff

Added routing for decks, players, locations, and beginnings of the users
pages. Also added routing for a calendar (soon to be moved to a top-level
folder), an analysis page, compare page, create, details, and search
pages. Filled out create page and fiddled a bit with the index summary for
tournaments. Fun stuff.
