Version 2.0 hotfixes

I wasn't sure if this warranted an update but I'll post it here anyway!

I've pushed two hotfixes to Spritesy. The first fixed a sprite data bug, and the second a UI bug that caused the background to become glitched.  I decided against making them a full 2.1 update, as I've already started work on a feature update (which will likely be 2.1). So look forward to that!

Thanks and enjoy using Spritesy!
