These changes break compatibility with the current Tilesheet system.

Changes:

• Tilesheet is stored in the Object data instead of the Scene or Material data
• Each object can only have a single Tilesheet (no need of multiple Tilesheets in a single object)
• Added events per action
• Added flipX and flipY properties
• Added "Slice" to fit the UVs based on the tiles X and Y count

With these changes the Tilesheets also work from linked blend files.

Basic setup:

• create a mesh with a material and set Object > Armory Tilesheet to true, this is going to be the root mesh
• map its tiles in the UV editor
• for each new action create a new mesh object
  • set Object > Armory Tilesheet to true (in order to see the animation during runtime)
  • set is as child of the root mesh
  • map its tiles in the UV editor
• add a new action with Object > Armory Tilesheet > Add Action and give it a name
• select the proper action's mesh in Object > Armory Tilesheet > Mesh

TODO:

• add flipX and flipY to Object > Armory Tilesheet properties
• add button to auto configure the UVs based on Tiles X and Tiles Y properties
