[Rev 01] RFR: 203: git-pr: add flag --jcheck to run jcheck as part of git-pr create

[Erik Helin]

> Hi all,
> 
> please review this patch that adds the flag `--jcheck` to `git-pr create`. As
> the name suggests, adding the flag `--jcheck` to `git-pr create` will cause
> `git-pr create` to run jcheck on the commits that will be part of the pull
> request. Since not all messages are relevant for commits that are to be part of
> a pull request (i.e. commit message errors do not matter) I added a new flag to
> jcheck `--pull-request` to filter out those.
> 
> I also had to some slight refactoring to `GitJCheck.java` to allow it to be
> called from other Java code.
> 
> Thanks,
> Erik
