Moved library into a subdirectory, renamed to init.lua

This just makes things easier to copy the library into a project or add as a git submodule.

 If you want to build the documentation yourself for whatever reason then:
 
 * install [LDoc](https://github.com/stevedonovan/LDoc/)
-* Run `ldoc.lua peachy.lua -d docs`
+* Run `ldoc.lua lib/init.lua -d docs`
 
 This will build them into the docs directory.
 
 # Limitations
 * By default Aseprite will export a **non-relative** path as the image file. This is problematic because LÖVE will refuse to load it and it's non-portable. There's a workaround listed [here](https://github.com/aseprite/aseprite/issues/1606). Either specify the image yourself in `peachy.new`, edit the JSON manually or use the CLI.
 * Exported sprite sheets **must** be exported as an array, **not** as a hash table.
