util.dataforms: Exclude descriptive text fields from forms of type 'submit' The receiving end presumably already have the original form, so these potentially long text fields are of little value.

util.dataforms: Skip all fields for the 'cancel' form type XEP-0004 says: > a data form of type "cancel" SHOULD NOT contain any <field/> elements. The title and instructions don't seem to be of much value in this case either. I'm not aware of 'cancel' being used anywhere, so this should break nothing. Early return is always nice.

util.dataforms: Only include options in 'form' type forms Options should not be needed in other types of forms.

util.dataforms: Set default value for form type argument

mod_admin_adhoc: Normalize indentation

mod_admin_adhoc: Keep options for list-single in 'options' field where they belong Would previously not work due to #1177

util.dataforms: Detach generation of options from values (fixes #1177)

util.dataforms: Add failing test for #1177

mod_pep: Return true if all node config checks passes (fixes configuration) util.pubsub would treat the default nil return as falsy and reject all attempts to configure nodes
