Various bug fixes:
- brief release descriptions weren't working
- cloning parts was crashing
- various issues with top collector rank computation
- API response for missing info had extraneous junk
- "dateAdded" retrieval for both parts and products was broken
- bulk email was not filtering on product ids correctly (not that we use it much)
And other odds and ends. Thanks to Engledogg for discovering and reporting most of this.
Two more big refactoring projects, folks, and then we'll get back to new features. Thanks for your patience.
