Title: slightly more forgiving git-delete-merged-branches

```git-delete-merged-branches``` now asks if a branch should be deleted and it never deletes master branch
There is a new ```--force``` option to suppress confirmation prompts.
Also - it is now written using git _plumbing_: ```for-each-rev```, ```rev-parse```, ```rev-list```.
