This commit include lots of changes for pose editor.
Before, we use buttons to represent the transform controller for bones;
Now, we use nodes and edges to represent the bones, just like the nodes and edges for representing the guide spheres for mesh generating. There are advantages by doing this. Firstly, The edit UI for both mesh and pose are unified, secondly, it is possible to set a reference sheet for pose editing now, this is very important.
This new pose editor is inspired by the Eadweard Muybridge's work.
Refactor outcome. Move processes of outcome to separated files, and leave the outcome class as clean as possible.
Normal export in glb format is been fixed.
Ambient occlusion baker is been temporarily removed.
Add a crc64 hash check for history keeping to avoid repeated snapshot.
Besides, before, there is a logic error in the undo implementation, which recover the most recent snapshot from undo stack, so user need undo twice and at the second undo get the expected result. This incorrect behavior got fixed.
Many source file name and data type are prefixed by "skeleton" before, now all are refactored.
The class MeshResultContext represents the outcome of mesh generation before, now we have material, pose and animation, so we just rename it as Outcome.
