add autoconf to GBs deploy script

gutteball's deploy script was not properly generating the gutterball.conf. You need to create a custom.yaml similar to the one used by Candlepin in the gutterball directory. Then deploy using ```bin/deploy -a``` I had a checksum violation on some of the liquibase files.

```
Updating Database
Liquibase update Failed: Validation Failed:

          db/changelog/2014-10-06-14-45-create-gutterball-schema.xml::20141006144514-4::awood is now: 7:aa988e2262f7f9fa163a957e2fff4ce9

```

So I had to use ```bin/deploy -gal``` which deploys Gutterball using the autoconfig, logdriver and regenerates the DB. This seems to work.
