Preset load/save system

[Luadih]

Description

A preset load/save system which could be implemented by creating a null with all the settings in it

• I have written a concise and meaningful title.
• I have searched the existing issues and this new issue is not a duplicate of any.

Note to self: This could actually speed up the preset creation system too.

Edit: I actually meant preset in the current preset way, that it just applies the settings to UNITE, the proposed change at the time was to export and import outside of UNITE

To make presets work in a sharable way and make them really compatible what could be done is:

Overview

1. Make presets save the data as a dictionary (can be json, though it would be better if it isn't), in case of a variable integer value like lights, panels and hdri's, save the name.
2. Improve the modules system by creating a single null representing the pack/module, also save the version in it, to be able to export them into the presets and make them detect when an older version or the current version is already in UNITE.

In steps

• Add versioning to modules
• Make importing a module into UNITE create a metadata null naming its contents and version
• Add a prefix to the elements that need it (lights & panels), at import time
• Show modules imported in a list (This is optional for now, but would be good QOL)
• Create import and export system for presets using dictionaries and include modules used in presets

Also job for later but in part is related to this: Add a null with a "key" to module and preset containers to only try to import to UNITE things that are valid to the current version.

(I may be forgetting something since, I only thought about this whole process in the morning and decided I should write it some time after)
