High five, Hive Timers!

A quick little update to fix a construction menu bug where build options were being displayed regardless of whether they'd been researched or not.

I also added an effect to the effect tray that indicates Queen age/lifespan. This information hasn't really been present in-game till now, and I'd bee wracking my brain for a good way to display it that didn't require more HUD clutter on top of what's already there. It turns out that a solution was in front of me the whole time \o/

Enjoy!

Full changelog:

• Fixed all buildings construction options being available regardless of research status
• Added effect indicator for current Queen(s) to indicate lifespan
• Added worker versatility research item icon
• Updated beesitter, defender, builder, forager and queen upgrade icons
