Add TexturePacker and Tutorials

[CodeAndWeb]

Hi,

TexturePacker supports LibGDX almost since the start of the project. https://www.codeandweb.com/texturepacker

There are also 2 tutorials available:

• https://www.codeandweb.com/texturepacker/tutorials/libgdx-sprite-sheet-tutorial
• https://www.codeandweb.com/physicseditor/tutorials/libgdx-physics

The first one is a quick intro into creating sprite sheets, the other one a more detailed tutorial that also supports physics using shapes created with PhysicsEditor (https://www.codeandweb.com/physicseditor)

It would be nice if you would add them, too.

Best
Andreas
