Colonist Errands 2.0.0-beta.42 — the defensive line stands between the raiders and the colony

A forced raid on beta.41 showed the alarm chain working end to end - the dusk warning, the pinpointed direction half a minute before MineColonies' own horde message, the alarm, a guard running to warn the player - and the automatic defense line placing zero towers: every post landed in the sea.

Fixed

• The defense line was anchored at the colony's bounding-box corner. For a colony that sprawls in the direction of the attack, that corner can lie far beyond the raiders' spawn - here 110 blocks behind them, in the water, so all 13 towers were skipped. The anchor now lies on the axis of the attack just past the outermost building in that direction, and never further than three quarters of the way to the raiders' spawn, so the line always stands between them and the colony.
• Water is no longer a dead end. When the chosen stretch has no dry ground, the line pulls back toward the town hall eight blocks at a time until half of its posts are dry - and says so in the log. Only when nothing between the border and the town hall is dry do the towers stay on their normal tasks.
• The same rule applies to the defend_here voice command's border and raid modes, which now report "every spot for a line there is water" instead of silently placing nothing.
• A line formed at raid start (when the raid was not pinpointed in advance) is now also released by the twenty-minute cap.
