Feature: Ignore VCS Root names

If a comma separated list of VCS root names has been specified, a revision (hash) belonging to that VCS root will be ignored and Stash will not be updated.  

Useful when you have multiple VCS roots per build configuration

Example: 1 VCS root for the code, 1 VCS root for deployment tools.  You don't want the deployment tools to be updated with a build status.
