Help intent shake-up no longer gets you up if you're voluntarily resting

About the PR

Does just that. Help intent shakes no longer remove the resting status, so if you're voluntarily lying on the floor you won't be shaken upright.
If there's still a want/need for a way to get laid-down people up, I could add some other method- maybe an aggressive grab always stands a person up if they're resting but not stunned/weakened?
Do note that if you're stunned AND resting, you'll have to manually stand up even after the stun is removed (by the shakes).

Why's this needed?

It's annoying when you're intentionally trying to lie on the floor for whatever reason and people keep shaking you upright. Also annoying when you're trying to fake death and people keep RUINING IT
