Improve geometry section in Property editor to support most of the basic use cases

• Re-arrange X, Y, W (width) and H (height) controls
• Move origin, Z, rotation and scale from Advanced tab
• Add actions
  • Flip horizontal (around selected origin)
  • Flip vertical (around selected origin)
  • A button to maintain width and height proportions
• Rename as Transformation?

Why

• The geometry-related features are now scattered between two tabs
• QDS is missing hygiene features that are in other prototyping tools
