Added function to added class to all inputs.
Removed firebug code.
Removed ngboost and ngcom translations.
Form can now define groupings (used in __toString and later templated).
A theme can now contain a file (form_css.php) that defines default classes for inputs, labels, and element groups.
Label is now a class and not simply a string.
Inputs can now have placeholders set.
The required check in the javascript now uses blur instead of change. A blank field changed is still a blank field, so the error check was not firing.
This is work in progress.
