Multiple scripts per container

Problem/Motivation

I've had a need to be able to put multiple Tag commander scripts per container but current settings form only allowing to put one per container.

Proposed resolution

I've created a patch that explodes the value of the field (separated by ";") so that we are able to put multiple URLs.

User interface changes

Added to the description of the two fields some info about the separator.

Do you think this is a feature that some users would find useful?
