Fixes #255
KSP after 1.8 is cacheing more PAW fields. In 1.10, the created event buttons hang around and don't get cleared by PAW creation, only by refresh. Catch the PAW show event and request a refresh if one is requested.
Refactor UpdateUsedBy a little. Every tank PartModule iterating over every vessel PartModule to build the UsedBy mapping may need analysis
