Merge pull request #133 from Animated-Java/experimental

Update main to v0.3.5 (Early Access)

- Removed texture size project setting in favor of automatic texture size detection.
- Added Animated Java Rig start page
- Extracted model DFU into it's own file.

**Major Fixes**

- Fixed `next_frame` not doing anything.
- Fixed commands keyframe commands input not updating when selecting a new keyframe while already having a keyframe selected.
- Moved `stop_all_animations` function to the correct namespace.
- Fixed AJ preventing texture deletion in external model formats.
- Fixed exported Rigs being rotated 180 degrees on the y axis.

**Fixes**
- Fixed lack of scrolling in variant properties dialog.
- Fixed export version namespace overlap.
