- Added a death check to voice manipulating code. Fixes Issue 1244.

- Made a proc for grabbing which updates the grab status, as it is usually done in the grab's process, then made tables update the grab and check if the grab still exists. Fixes Issue 1285.
 - Made the blind check remove the blind screen if they're not blind but the layer is set to a non-zero layer. Fixes Issue 1286.
