Respect user settings sent on login

[mellowagain]

Currently, Shiro does not respect all options sent in the login body.

Login body:

Username
MD5 hash of the password
Version|UTC offset|Display full location|Colon seperated list of MAC addresses which are MD5 hashed|Block non-friend PMs

Current options which are not respected:

• Additional Info index 2: Display full location
• Additional Info index 4: Block non-friend PMs

Shiro should respect these options.
