[crossfire] metaserver differences and code

[Rick Tanner]

Some local changes have been made on the US Metaserver for error tracking.

Now more servers are reporting or showing up on the US metaserver list.


Some discoveries:

archbase, mapbase, codebase are currently limited to 20 characters. 
Multiple servers exceed this 20 character limit.

version field also has a 20 character limit, but with the new git 
version info, that exceeds the 20 character limit as well.

The US Metaserver mirror was tweaked to allow 64 characters in those 
four fields, and that is when additional servers showed up.

The hosting architecture for the EU Metaserver does not enforce the 
character limit on any fields, so this contributes to why more servers 
show up in that list then the primary metaserver 
(crossfire.real-time.com) and the US metaserver.
