When comparing two instances of `EmailAddress`, the domain should be treated case-insensitively #11

From RFC 5321, section 2.4:

The local-part of a mailbox MUST BE treated as case sensitive. Therefore, SMTP implementations MUST take care to preserve the case of mailbox local-parts. In particular, for some hosts, the user "smith" is different from the user "Smith". However, exploiting the case sensitivity of mailbox local-parts impedes interoperability and is discouraged. Mailbox domains follow normal DNS rules and are hence not case sensitive.

Should be fixed in b3e5205b4efdc83832f230d8eb6894fd00a9ec32 which will be released as 0.2.4
