Mms: Add the ability to select recipients from a checkbox list
When creating a new message you have to write some letters from the
contacts you want to add and select them by clicking on it.

This can be annoying if you want to send your message to several contacts.
With this change you can manually select numbers from contacts and groups
from a checkbox list.
