Feature request: Modified patches remain modified until saved or recalled

[elauria]

I would like modified patches to remain modified even as the P600 changes to other patches and back
Currently moving away from a patch and back resets it to its last saved state
I would like to be able to make changes to a patch, move to other patches and come back to the modified patch without recalling its saved state, still with unsaved changes present

Example:

1. Choose patch 00
2. Modify parameters like envelopes, oscillators, etc (patch is now modified)
3. Choose a different patch, i.e. 01
4. Choose patch 00 (go back)

Current result: patch 00 is unmodified
Desired result: patch 00 has modifications made in step #2
