1.4 Beta - Now Pure Script Based

• Major: The C# resource pack generator is now gone - DModels is now 100% script based, including for model loading.
• Internal: The script has been split into multiple files and organized.
• Internal: A lot of cleanup and documentation work has been done.
• Added: There are now tracking_range control options in the config and spawn task
• Added: There is now a fake_to option on the spawn task.

Also, special thanks to @FutureMaximus for PR #7 which implemented the script version of the animation loader, and for pushing an interest in expanding and empowering DModels, with more feature PRs planned and addon projects already in the works!
