- Added support for wildcard branch name filters

 -  Used the git log --branches=<shell glob wildcards> option in method ProcessGitLog. If wildcards are in the filter, then the --branches option is used. Otherwise, just the branch filter without the --branches option is specified, which give the original exact match functionality.
- Code cleanup and static array extraction

- Converted tabs to spaces.
- Pulled the array of shell glob characters out to a static array.
Merge pull request #1815 from gregsohl/BranchFilterWildcard
