gd Map overlays for AOI, TSG
Updated l10n-track.
SotBE S17: make all the guards loyal
SotBE S17: make reinforcements appear at southern edge of map

… rather than some hexes north of the edge.
SotBE S17: scroll to location where reinforcements appear
SotBE S17: some tweaks to AI reinforcement events

Change their number, timing and order of messages.  Also put units out
there first, then show the messages.
SotBE S17: make the enemy AI leader passive

… so that one cannot make him leave his keep suicidally.
SotBE S17: decrease enemy AI aggression during nighttime
SotBE S17: start schedule at morning, not dawn

Makes it a little harder for the player that way in combination with
the other changes.
