Made some changes to server network code to hopefully fix disconnection issues that players have been having recently.

Fixed level difference value in PK message to 20 from 30.

Below changes were already active on the server before the update just letting them be known:

PK Changes:

Changed PK level difference to 20 from 30 and allowed grey and low moral characters to be attacked by anyone.

Characters that attack a grey or low moral character will be flagged into a mode where they can be PKed by anyone at any level.

This is to allow PKers to deal with characters that attack them while grey or low moral that are not within the PK level difference.

The character will be flagged for 1 minute.

The 1 minute will reset each time that character attacks any grey / low moral character and the flag is also removed upon death.

The reason for flagging on a timer is so that other grey / low moral characters can also get involved and attack the character attacking them etc.

Switching Mage Type Fix

Removed the enforcement of 200 magic skill cap. It is not needed and was causing an issue where Blue magic skill would be decreased instead of White or Black magic skill.
