0.10.2: Bug fixes

- Fixed a bug that prevented saving a game if a set of certain items didn't exist
- Fixed bug where a nail that passed through more than two boards caused a bug in the generated assemblies when it was removed.
- Fixed bug where a 'grab' hold on lumber would be converted to a 'grab-lock' hold after removing a nail
- Fixed a bug with the tape measure that caused the tape measure hand grip joint to remain limp beyond the time it should have been limp. Tightened it up right.
- Fixed null reference error with the dustbuster when you attempt to vacuum something that is static.
