Implement Linked Spell Reuse Timers

They started linked spells at OoW launch (I think)

At least canni was linked then.

This is rather user unfriendly, but that's live like.
Ex. the spells aren't actually put on cool down so you can attempt to cast them
still but you will be interrupted.

Titanium is particularly unfriendly with large differences in reuse times
