[+][SUG][PL] Make Talisman requirements visible during play

[WillLem]

This idea is courtesy of Armani, who has solved this issue in his custom NeoLemmix build.

We need some way of being able to view the talisman requirements during gameplay. If a talisman has many requirements, it can be difficult to remember them all and this can inhibit a player's attempt at the talisman, or worse - put them off attempting it altogether.

Armani solves this by displaying a clickable talisman button which opens a panel showing the requirments. The panel is updated live, so a player can also track their progress on the talisman in real-time.

This may be a good enough solution as it is, but I thought it best to open this up to discussion in case anyone has any other suggestions.

One possibility I can think of is that clicking the talisman button could adjust the skillset, save requirement and time limit shown in the panel itself. We can use different-colored digits (possibly) to show that it's a talisman requirement rather than the normal requirement, and the player can toggle between the normal/talisman values by clicking the button again. Progress feedback will be inherent; the display can revert to normal once any of the requirements have been failed.

The only downside to this idea is that a level can have multiple talismans, so we'd need multiple buttons.

Thoughts? Suggestions?
