@version 0.0.121

- Updated readme with some changes
- Refactored reach.form.js with the new changes to extend method in
core.
- Fixed compatibility bug in reach.shop.js
- Directive Updates:
- Directive instances now has a seperate dependencies variable for use
in directive extensions.
- Directive extensions are now handled in core and a seperate extend
method in the directive is no longer needed. The instance is now this
and all the dependencies that the directive has is passed on to the
extension as well. (Next I will add custom extension ability to be added
ontop of that again.)
- Refactored inject method a little.
- Fixed compatibility bug in reach.jsend.js service
