* feat(invite): be able to call numbers from the invite dialog
The major changes:
- Remove DialOutDialog, its views, redux hooks, css, and images.
Its main functionality has been moved into AddPeopleDialog.
- Modify the AppPeopleDialog styling a bit so it is wider.
- Add phone numbers to AddPeopleDialog search results. Phone
numbers are validated in parallel with the request for people
and then appended to the result. The validation includes
an ajax to validate the number is recognized as dialable by
the server. The trigger for the validation is essentially if
the entered input is numbers only.
- AddPeopleDialog holds onto the full object representation of
an item selected in MultiSelectAutocomplete. This is so
selected items can be removed on successful invite, leaving
only unsuccessful items.
- More granular error handling on invite so individual invitees
can be removed from the selected items list.
