Release 1.8.0

This was used to delete an errant '*' service that was accidentally created during service deletion. That was fixed in dokku/dokku-redis#126 - and the respective PRs for each service - and is thus no longer necessary.

The fix was done by utilizing pushd when iterating over folders instead of trying to get a subdirectory with a partially quoted path.

Closes dokku/dokku-redis#130
