Ceedling version should include the short SHA in the version identifier

It would be good if Ceedling would provide the short SHA in the version identifier, at least for Ceedling and in the best case also for the vendored dependencies, i.e., currently ceedling version reports

Welcome to Ceedling!
    Ceedling:: 0.32.0
       CMock:: 2.5.4
       Unity:: 2.5.4
  CException:: 1.3.3

and it would be nice Ceedling would instead report

Welcome to Ceedling!
    Ceedling:: 0.32.0-3ba12fa   <----- Short commit SHA
       CMock:: 2.5.4-blabla  <----- Short commit SHA (optional, but nice)
       Unity:: 2.5.4-blabla  <----- Short commit SHA (optional, but nice)
  CException:: 1.3.3-blabla  <----- Short commit SHA (optional, but nice)

otherwise you have to manually keep track of the used Ceedling version when using a pre-release gem as it always just reports 0.32.0.

Note: If this feature request is accepted, I am willing to create a PR.

Done! The latest Ceedling prerelease includes this much needed feature in the version output. It'll be a while until CMock, Unity, and CException get the same treatment.
