WS30 - Clear WS30 data on tile unload

Browse source 
Previously WS30 data from STG files - in particular road/rail/river
data - was kept permanently.

This change unloads it with the STG-level tile.  This is the right
level to do so, as it will be reloaded from tile when the STG file
is loaded again.
