Upgrade point spending improvements

[Omnia0001]

I do like the idea of creating ascension point presets and unlocking slots for diamonds. I would say there should be a max limit to it though as to conserve space on setting this customization.

Off the top of my head I can think of - Idle Setup, Challenge Setup, Pet Setup, and Tree-Cutting Setup.

So having a max of 5 custom slots to freely switch between should work.
