[#542] Add support for tileset animations

- Working with XML and JSON maps
- The animations seem to run too fast? They are faster than Tiled, for sure.
Update CHANGELOG
added a `toString()` function to me.Matrix2d
fixed the `isIdentity()` and `toString()` functions
added a simple test unit for `me.Matrix2d`

based on the glMatrix one, probably needs more edge case testing and
some cleaning
