Modified the commit comment PCRE to use named groups, and updated the VCS code accordingly. Performed a couple of renames of temporary variables in the process to make their use clearer.
Added support for commit message of format 'ISSUE_NO: (TRANSITION) Message' to the VCS integration. Added support for multiple regexes for parsing issue information from commit messages. Implements issue #1995.
Merge pull request #172 from azaghal/branch-32
