Some small changes for custom formatters. Added compile_time tag to boilerplate.
Swapping instances of dirname(__FILE__) for __DIR__
Added ARIA plugin for working with aria roles states and properties. Plugins can now add selector aliases as callables.
Added forms plugin: pseudo classes for working with forms.
Refactoring for more consistent mixin and referencing behaviour.
Referencing and mixins are now defered to a later stage of execution where possible so clearing up some edge cases.
