Add 'error-chain' to the main library

Use 'error-chain' here too. Seems like this will be a pretty useful
library.

Change the include in the 'meetup' `lib.rs` to allow us to export
`meetup::Error` instead of `meetup::errors::Error` to be consistent with
the error types of the other third-party libraries we're using.
