Core 1.4 specific changes.

Browse source 
* Ensure it can compile.
    * Removing vanilla 2.2 properties that slipped in to previous commits.
    * Rearranging i_tcp.c to avoid implicit declaration.
    * Complete rename of `IsNameGood` to `EnsurePlayerNameIsGood`.
* Add "BANFORMAT" header, for versioning support.
* Add conversion from 1.3-and-earlier format to new system.
* Don't ban the entire internet - convert zero-masks to the most specific ones.
