Update 0.954

As I'm working on projects using Baby 3D a few things came up already warranting another release.

Nothing too spectacular to go on about. Fixes to skyboxes have been long overdue I guess.

For that and everything else refer as usual to the changelog:

• changed B3D Box, Plane and Cylinder behavior property "Instance" to use clones instead of actual instances (this is Babylon.js internal) thereby fixing issues when using instanced billboards
• fixed potential crashes when using instancing and destroying objects
• fixed potential issues restarting/switching layouts while using the glow layer 
• added B3D Cylinder behavior property "Culling" which already existed for Box and Plane behaviors
• changed how B3D Cylinder behavior property "U offset" works when also using "Multi-face" - you can now limit the area the side texture uses with this value
• added B3D Plane behavior action "Mirror texture" which does what it says
• fixed Baby 3D plugin action "Create skybox" positioning the skybox not correctly (usually this did not matter though)
• fixed Baby 3D plugin action "Create skybox" not actually using the size you set in the action
• fixed Baby 3D plugin action "Create skybox" creating a skybox that could be obscured by using fog
• fixed Baby 3D plugin action "Create skybox" requiring .jpg files instead of .png files
• fixed Baby 3D plugin action "Create skybox" not actually using the set name internally
  
• fixed decals being displayed smeared in certain cirumstances (hopefully)
• fixed decals not being destroyed when destroying the mesh they're applied to
• added B3D Particles plugin action "Set vectors"
• changed Baby 3D action "Parent camera" to allow parenting of any mesh/camera to any mesh or camera
• added Baby 3D action "Look at target" similar to "Set camera target" but works for any mesh
• changed description of Baby 3D action "Destroy decal" to "Destroy decal (or any mesh)" reflecting what can be done - for example destroy a skybox
