Fixes to allow mongos to start up
- mongos will not start with dbpath
- mongos requires configdb
- stop including the default recipe as that configures mongodb, which you typically do not want on application host with a local mongos
Merge branch 'master' into fix-mongos

Conflicts:
	definitions/mongodb.rb
allow configdb to be specified by hand
Merge pull request #212 from jspiewak/fix-mongos
