[WorldMap] Add strength & ranged requirements to WorldMap AgilityShortcut icons & tooltip

[NinjaLikesCheez]

This change adds strength & ranged level requirements to AgilityShortcuts (lifted from the Wiki, might not be inclusive of all agility shortcuts) and uses those requirements in the WorldMap plugin to strike out icons which are not player usable.

Would be great if this can be merged.
