Supports exporting images & spritesheets with frame, direction, scale and output file name specification. Also added some informative arguments that simply print out some data.
The previous backup code was unnecessarily complicated, hard to read/understand and prone to errors. The new system simply stores the save and backup paths in the `Project` class, and stores the backup files inside `user://backups`, instead of having their file paths be in `cache.ini`.
This way, Pixelorama remembers the changes users make to the UI, without them having to go to Window, Manage Layouts and clicking on Edit, which was an unintuitive and slow way. Needs testing because bugs may linger.
This commit also adds a new `save_on_change` variable and a `save` method on layout.gd of the dockable_container plugin. Perhaps I should also add this upstream as well.
I also need to add a way to create new layouts based off the default ones (which are permanently stored within Pixelorama's pck file and cannot be modified), so users will always have the option to resort to the default layouts.
* Save pxos as zip files in disguise
* Load pxo files as zip
* Add a checkbox in save dialog to let users include the final blended images in the pxo or not
