Client

- Just import `birchwood.config` package rather
- Call `setDefaults(this.connInfo)` to assign default `db` values
- `nick(string)` will now fetch the maximum nickname length and ensure the provided nickname is in said bounds, if not then a `BirchwoodException` with `ErrorType` `NICKNAME_TOO_LONG` is thrown

Unit tests

- Updated unit test to test the updated value of `MAXNICKLEN` (which on BonoboNET is 30)
