Handle names with multiple spaces in them

[dallinski]

If a name has multiple spaces and the "first_name" or "last_name" variables are being used, prompt the user to select a name when they send the message. (One prompt per multi-space-name)

For example: If a contact's name is John Paul St Augustine and the template uses the "first_name" variable, when the user hits send, pop up a modal asking:

"What would you like to use as John Paul St Augustine's first name?"
(Dropdown values)
John
John Paul
John Paul St
John Paul St Augustine
