--new script action: RemoveSpawn. This removes a character's spawn info before it ever has a chance to enter the battlefield. For occasions where particular characters are specified by name among the <Unit> tags of a map, but they won't be there on turn 0 and you don't want them to spawn on the turn they're scheduled to show up.
One parameter: character name, with first and last names delimited by a colon. There are three additional, optional parameters: Y Coord, X Coord, and Spawn Turn. These can be used to drill down to a particular character if the character shares a name with others among the <Unit> tags.
For example:
RemoveSpawn Lord:Dakarai
will look for Lord Dakarai among the <Unit> tags on the current map. If he's found, and hasn't spawned yet, he'll be removed from the characters due to spawn.
