Bumped pod spec to version `0.4.0`
** Warning **
-- This *does* break backwards compatibility:
-- Some classes and methods have been renamed... e.g. `ALTextCell` is now `ALTextViewCell` and `setValuesDictionary` is now `setValuesFromDictionary` for clarity and consistency throughout the project

However, the upgrade path shouldn't be too bad -- can be done with "Find and Replace" for pretty much everything.

This is a decent size update to the library... including adding support for `ALTextFieldCell` :]
Enjoy!
