[+][SUG][PL] Update "Lems Saved" count on skill panel

[Guigui]

This can work. Though make sure the Lems in hatch number is always visible.
Sometimes it disappears behind terrain, or out of the level if hatch is too close from the borders.
Maybe force it to display clearly when player mouses over the hatch ?

Making the minimal changes necessary to begin with, we now have this:


From L-R: Lems yet to spawn, total lems available, (save requirement - already saved). The last of these now answers 2 questions: what is the save requirement (which can still be viewed by mousing over the icon)? How many are still to be saved? And meanwhile doesn't create any questions like "why is this a negative number"? Good.
.
.
.

All lems have spawned. 15 are available, 5 have been saved (so 5 have still yet to be saved)
.
.
.

10 are available, and the save requirement has now been met (we show 0 in green).
.
.
.

After a single additional lemming is saved, the save count starts to show the total saved. At this point, 5 are still available and a total of 15 have been saved.

...

We could probably continue to show hatch lems on the panel tbh, there's not really any need to remove it and create UI junk elsewhere. I'd still prefer to keep it as the first item displayed, because it will normally be the first to reach 0 and become no longer relevant, and it's the first number that possibly can change.

The above could probably be enough just by itself to meet the OP's needs, but perhaps additional UI such as a light-up or checkmarked exit could provide further feedback.

Thoughts so far?
