Fix #965 Remove required attribute from state

Removed the required attribute from the state input in the extended
settings. The included fields are intended to just be examples, but we
shouldn't require the user to update the file to make Bonfire usable for
them.

Language should fallback to English, restored loading lang files from
module by calling $this->lang->load("{$module}/{$module}"); when the
module is not already in the loader's current list of file paths
