Novaboard Updates

This time I worked on a few features I wanted to build, instead of only polishing  

The new features are:

- Objects: quickly reusable art. Rotate and scale, without losing pixels. Edit and all copies change at the same time (old clip layers were renamed to external objects)

- Custom brushes: any file in your workspace can be a brush, even if it is animated

- Brush across frames: a toggle that stamps each brush frame on the next canvas frame. One click and you have an animated star in the sky

- Workspace: works like a file explorer, with selecting, opening and deleting multiple files at once

- Double esc takes you back to the workspace, keeping your tabs open

- Gamepad support: I saw a video on X where a Switch controller was used to help with animation: Next frame, previous frame, toggle onion skin. So here it is, any gamepad button can be bound to any command

- General fixes and improvements

As always any feedback is welcome, as well as voting for the app on itch, Lospec software list, and soon enough other stores!

Changes:

- Option for brush pattern painting

- Erase can use custom brushes

- Every tool now has some shortcut

- Indexed files have palette slots

- Iso draw improvements

- fixes and improvements

As always, all feedback is welcome.
