Feature: Introduce regex pattern to infer a branch title from

[jwu910]

Would it be possible to have a configuration property containing a regex pattern that GH could use to name a branch when pulling a PR down?

For example, if someone sends me a PR titled TICKET-1234, I could give GH a regex pattern that matches some TEXT dash NUMBERS and either grab that from the PR title, or from the latest commit as this is also a common practice.
