[v1.0.5+] Restart Sustains

[Zizzo]

Another fun fact: in Hirumakai's Spellsword addon, Air Strike and related talents will automatically "bounce" the Elemental Destruction talent if you have it sustained, presumably to update its provided bonuses for the elemental stance you just automatically switched to. Unfortunately, we were misidentifying that as a loss of the Elemental Destruction sustain if it's marked, for a false positive on the "you just lost a sustain" visual effect. We detect and suppress that in v3b.5, just released.

v3b.6 fixes a bug reported on te4.org: we were assuming that Actor:preUseTalent() would only return false in our use case if the player didn't have enough resource, and that we should therefore wait for resource recovery to catch up. We now make an effort to distinguish between that case and other talent preconditions failing (in the reported case, for instance, trying to restart Berserker Rage while wielding a longsword and dagger); in the latter case, of course, we ignore the talent when deciding whether to stop resting.
