Added a new setting: MAX_UPLOAD_TOTAL_SIZE

Form now keeps track of the total size of the uploads to keep it under
a set limit (default to 10M) e.g. to keep the total size of the message
within some email server limits.

Thus might be backwards incompatible unless the total size is redefined.

Bumping the max_length for the field_class to allow adding longer class names.  I ran into trouble when trying to add a phone number field form with a class name of "phonenumber_field.formfields.PhoneNumberField" (which is longer than the current 32 char max) to the FIELD_CLASSES used in the combo box for adding a new form field.
