Should localgov_forms_date be a seperate sub module?

Problem/Motivation

From Github #119
Seems strange that address lookup is the route of the module, but the date widget needs the module enabled. Been tripped up a few times doing testing, see also #37.

Either:
- This module should provide all elements in the main module, with enabling or disabling of elements handled by Webform and site builders (BHCC disables Localgov date as our BHCC_date field extends it, so we have the module enabled but disable the element anyway).
- Seperate each element into a sub module, so Address lookup becomes it's own module.

Ideally do this before 1.0
