Initial commit.
	- Added "play" app
	- Added .gitignore to ignore .pyc files
	- Created "Game" model
	- Created "index" view
Made game board.
	- Added image assets: board.png, x.png, o.png
	- Added stylesheet

	- Added jquery

Added Strategy class.
	- Strategy class handles all logic for determining the next
	  move.
	- Added utilities.py for functions not related to views or
	  models.
	- Added json_response() function.
Actually, it's dinner time.  I'm going to take a little break and get
back to this in an hour or two.  This file is just for documenting
the gap.
Back to work!
Strategy.next_move() now correctly calculates the next move to take.
Wrapped up development.
	- Added AJAX endpoints for getting the game state
	- Finished building-out the strategy
	- Improved the model's pretty-printing code
	- Updated styles and HTML
	- Removed about.html after I realized I didn't have anything to
	  write there
	- Auto-initialize the board with previous game state
	- Probably some more stuff I'm forgetting

That's it!
