Adding ability to cycle piece blocks by pushing 'x'
Adding some basic images for numerals + a font collection
Pieces no longer cycle backwards
Fixed initial piece having ability to spawn a 5-block
Adding sounds and rudimentary score tracking (for testing + fun)

This won't actually last, it's going to be written out somewhere else,
but now it's officially a time-waster you can mess with
Changing drop button from space to up.
Add sounds for movement and cycling piece blocks
Merge branch 'sounds' into develop
Adding conf.lua for better-er LOVE support. No more "Untitled"!
Adding class for Game, which will do all the game state logic... hopefully.
Broke the game into various Game states now, much better.

Lot of fucking work, but worth it, I think.
Merge branch 'class-game' into develop
Pieces can now be moved down a square without crashing
Removing outdated/unused conf.lua stuff
Redid a bunch of scoring stuff, and fixed clear detection against duplicates.

Fixes #1. Done by checking blocks behind the current test.
If they're the same, skips checking and moves on.
Idea being that if we have something like this:

1 1 1 1 ...

...if we're on the second 1 and the one behind it is also a 1,
we would've caught it already.
Removing some debugging output
Merge branch 'develop' for release, yay
