my micro room v 1.2 - micro update

Hey, everyone! This is a quick micro-update (before the mini-update!)

I've added the ability to change the flooring.  Plain wood looks a bit boring, right?

Also, I've made a few other minor changes:

• new kittens
• some new rugs
• micro optimizations

Next up in the mini-update:

• new pets
• new furniture (brand new!)
• and wooden figures in various shapes — rectangles, sticks, etc., so you can make new... stuff? items? go for it!

That's all for now! Thanks for playing!
