Added byond_version checking to client/New(). If a client's installed byond_version is lower than MIN_CLIENT_VERSION then they will be autokicked.

It is not in effect yet (minimum version is v0 :P). However, <b>everyone must update to at least byond version 494 by the end of the month, or they may find themselves unable to connect</b>.

If anyone has a legitimate reason for why they need to use an older version (linux, language-support etc) please get in touch and we'll work something out.

Why is this even necessary? Encouraging the payerbase to keep up-to-date BYOND clients will allow us to implement newer BYOND features reliably. It also makes sure all clients are behaving similarly.
