Merge pull request #11 from quinkennedy/admin-flag

added targetType enum to direct messages to admin/client
fixed issue with initial config message not being forwarded onto the admin.js API handler. Fix is temporary, it just checks messages that don't have the targetType to see if they are an array. We should make this explicit but can't do so without breaking the main admin.
Updated file names to the latest sb library.
