Feature Request - Unit ID Ranges

[robertlynch3]

As discussed in the 171.

My county uses radio ID ranges based on towns, so 1000-1999 is town A, 2000-2999 is town B. It would be a nice feature to be able to setup a range an have an 'catch-all' label for them. If an ID has a unit set already, that should take precedence, but if not, use the label from the range.

Even further, maybe some sort of Regex, so if I say 1000-1999 is town A, I can say grep everything after 1 and assign that to the radio number so 1005 can be labeled Town A radio 5.

Postponed until v7.0 because it requires a database change with data migration.
