VersaTile Versions Save

So, it's finally done. A lot of fixes and improvements were done since the last release and i'm quite happy what VersaTile has become.

Stuff that was changed:

• Export is fixed and now exports with texture
• The default tileset is now by kenney.nl
• Grid snapping for the mouse now works as expected
• The texture dialog has much improved
• Textures can now be updated after model creation
• The sprite sheet is scrollable when too large
• The camera can now be centered on the selection
• There is an options dialog with useful options (ground plane, ...)
• The grid alignment can now be set into manual mode

Now, go and make awesome models with VersaTile!

This is a first pre-release of Versa-Tile, containing all features for the first release version.
