Added license

It makes sense to actually have the license this is supposed to be
under.

Attribution NonCommercial ShareAlike 4.0 International: You can do
pretty much anything with this except bundle it in commercial software
(more because of Nintendo than anything else).
Documented InputWritr

Also fixed up associated variables and function calls elsewhere.

Device motion set to rely on "Tilt Controls" being on, even for the mod.

Fixes #11.
Added Grunt handling

The concat and uglify modules are used to place FullScreenMario.js and
FullScreenMario.min.js in /dist. Default files are renamed to index
files to represent where they belong.

Also fixes a few errors with UserWrapper from the last few commits,
whoops.

Partial fix for #56 - will have to automate .css files and the move from
index-dev.html to index.html.
Added more grunt-related changes

As in, ran grunt again.
Fix for large scoring on FireFlower collisions

Yup.
Solidified build process

Added /dist to gitignore because it now has copies of Sounds, Theme, and
Fonts. In the future it would be nice to replace Fonts with PixelRendr &
PixelDrawer and Sounds with a JSON-based AudioPlayr (see commits related
to AudioPlayr/AudioPlayrNew).

Moved ImageReadr into /src/utils because that's where it belongs.

Removed old, unused images from Theme.

The root index.html now works and has Grunt processing it into the
dist/index.html.

Fixes #56.
Deleted index-dev.html

It was time.
Update README.md for Grunt-based writeup.
Removed dist/FullScreenMario.js

It was moderately unnecessary. Also updated README.md to be a bit
clearer.
Fixed index.html referenced old FullScreenMario.js

Whoops.
