[+][SUG][PL] 'Use at least X of Skill' talisman

[WillLem]

This has now been implemented in SuperLemmix. We can give it a try there and see if it's any good.

It's been done as a 'Min-Max' skill limit, to keep the interface as clear as possible and to allow both limits to exist for the same skill.

Example UI:

If a skill has a minimum limit of 5 but no max, it will show as '5+' and 'Use at least 5'.
If a skill has a minimum limit of 5 and a max of 10, it will show as '5-10' and 'Use at least 5 but no more than 10'.
If a skill has no minimum limit and a max of 10, it will show as '0-10' and 'Use no more than 10'.

SLX Editor support has also been added.

SuperLemmix 3.0.3 should hopefully be released in the next 5-7 days.
