Bug fix and minor feature update for HoloBlocks

HoloBlocks has been updated to resolve some bugs and annoyances, available in the store now.  Here's the change list. 

  1. Fixed a bug that caused the "finish" button to disappear during room scan if you walked behind it. 
  2. Scanning UI now follows you instead of remaining fixed in one place.
  3. Fixed a bug that caused a frame-rate hit when clicking on the spatial mapping mesh during room scanning
  4. Menu can now be moved and resized after placement using the move and resize tools
  5. Menu automatically orients to the user, so you don't have to always face the same direction as when it was initially placed
  6. Menu can no longer be collapsed
  7. Other minor bug fixes
