Add Phaser Files

Not sure what files are needed or how best to load them all. I will need
to minimize them at some point. Phaser's documentation has not been
updated in some time...
Merge branch 'gh-pages'
Create README.md

explain the odd folder structure
oh, there's the unified min js

phaser... you need to update your docs...
phaser license
possible texture images

with links to sources
load phaser
grass tile ?

good enough for development. I am seeking a proper graphics designer...
lay some initial tiles

Merge branch 'master' into gh-pages
