Subject: [PATCH] ConnectionInfo

- Updated `string getDB(string)` to `T getDB(T)(string)` which will now attempt conversion to type `T`, on failure to do so it will return `T.init`

ConnInfo

- Added `setDefaults(ref ConnectionInfo)` which will set defaults in the `db`, namely so far it sets the `MAXNICKLEN` to `9` as per rfc1459

Package (`birchwood.config`)

- Now publically imports `setDefaults()`
