New and improved zone header and timeofday code

[Scruffy]

I've posted my zoneheader and timeofday patch to the Emulator on http://www.geocities.com/scruffyeq/coder0/ . Here's a brief summary of changes:

-New default zone header data. The new default has a new sky, black fog colour, and a clip plane of 1000-20000 .
-New zone header file support. EQEmu now trys to load ./zone/<zonenamehere>.cfg when zoneheader is requested on zone load. The zoneheader format is the same format as EthernalQuest 3.x ./<dbname>/world/<zonename>/info files.
-Added the ability to change zoneheaders on the fly (for all players in the zone) using the #zheader command. The command is GM+ and has the syntax: #zheader <zone name | none> - None uses the default hardcoded zoneheader data.
-New struct for time of day.
-The time/date will now be set to 9:00 AM on Jan 1st, 1 when you load EverQuest.
-Changed #timeofday to set the date to Jan 1st, 1 when it is used.
-Added the ability for GM+ to set the time and date in EQ by using #date. Run #date for exact syntax.

Have Fun!!
