When not adding fallback, use default behaviour

Fix removeFallbacks

mapBodyMaybe helper

typo

Remove any sims/fallbacks before adding our own

Had it backwards

Generate fallback for OOB with no body

Stop blocking whispered URLs

Because whispers are blocked from going to SMS anyway these days and so
it's just getting in the way of other uses.

Indicate what jid to reply to

spx too specific, ogg too generic for audio/ogg

Hack to always return the sip proxy for JMP

It happens to always be the same at the moment, and this will reduce
number of stanzas dramatically

StatsD for presence probe to tel

List possible actions so user knows what to do

Ask for action when filling out a form with no fields

Copy over new feature from cheogram-sip

Fix typo... again

Fix typo, this is not an avatar node

Never send presence response to ourselves

Strip whitespace from possible command invocation

Allow owners to message any JID from the phone number they own

Messages to user\40domain@component used to only work if the from domain matched
the target's route, but this adds another case where if the from has an assigned
cheoJid (aka phone number) that they own, we can route to the target from that JID.
