Add the option to prune empty commits (issue #27)

This feature removes commits that- after the cleaning process -contain *no*
file-tree change when compared to their parent commit. This would be
because the cleaning process has cleaned away whatever content it was that
was _changing_ in the original commit.

The option is off by default, it's activated by using the
`--prune-empty-commits` flag, eg:

$ bfg --delete-files foo --prune-empty-commits
