Alpha 5 patch 9 hotfix 17

Added/changed:

• Stone deposits are now allowed to be blocked (also solves the problem with bridge demolishing and bugged old saves)

Fixed:

• Brewery hop kiln cowl turned to the wrong wind direction (yes it's a thing)

• Another case of blocked rowhouse

• Water navigation was messed up a bit (will stay that way in saves between hotfix 11 and 16)
