Allow merge and push branch in one click

Please allow users to merge a branch and push in one menu click.

Now it's like this:

- checkout the destination branch

- right click on the branch you want to merge

- click on "merge..."

- wait for merge to succeed or fail

- click push

I'd like to be like this:

- checkout the destination branch

- right click on the branch you want to merge

- click on "merge and push..." *

*push should be done automatically when there are no conflicts
