(CPR-50) Change order of build-data

This commit goes in and changes the fetch.rake task to allow for project
data to overwrite team data. Before it would fetch the project data then
team data from the build-data repo, overwriting anything that is the
same in project. Since we currently do not have any intersections
between project and team datas this should not break anything.

(CPR-50) Change order of build-data
(MAINT) Move git utilities into library

This commit goes through and takes all of the git based utilities in
00_utils.rake and moves them to their own ruby file in packaging. It
also goes through and finds every use of the old version and replaces it
with the new one. Finally it deprecates the old one so as to show a
warning message in the event the old one is still used. However it won't
break, just warn.
