move panorama's to fancy menu's build in panorama tech

[UltraPuPower]

Title says it all tbh
As per discord

Cycling panorama's inside the same layout seems to be impossible: ref > Fancymenu discord support

Possible issues/reasons we wouldn't want to do this

• Adding a new panorama becomes a bit more of a hassle, nothing much but small annoyance
• Changing Main Menu becomes more time consuming as you will have to sync across all layouts
• Slight lag spike when swapping menu's

Last item can possibly be mitigated by setting randomonlyfirsttime to true, but that would mean swapping a panorama by simplying entering and exiting a menu is no longer possible, and the panorama will only be picked at game launch.

To see what I mean with slight lag spike, just load up the branch and go to singleplayer and back to main menu a few times

@UltraPuPower need to fix merge errors unless it is just being stinky (need another party to confirm)
