2019-06-22 Build (preview-41)

Small update today with some adjustments to research timing and fixes for end-game bugs that I probably should've spotted sooner.

I've been looking at a bunch more research stuff that's not enabled yet - bee efficiency upgrades and advanced building variants. Not sure when that'll be ready to make it into a build, but providing multiple paths to hive productivity/efficiency/health that go beyond just expanding makes the game feel a lot more interesting.

Full changelog:

• Increase duration of barracks, honey, and jelly refinery research
• Fixed queen not dying (for real this time)
• Fixed tutorials being shown when starting a new hive with a new queen
• Fixed research being reset when starting a new hive with a new queen
• Load shortcut (L) now loads most recent save instead of oldest save
