Pathfinder didn't search path through ship bridges.

[Cherry Soup]

Pathfinder didn't think Ship Bridge tiles is walkable place. At least for emigrants and native-barbarians.
As example: try to build bridges on Tolentum map and place houses on other side of the lake.
Also, native-barbarians produce tons of lags, when they can't find a way to the player's building.

fix #309. Improved ship bridge draw and init options.
