Voice lock, experimental voice hide

Defucked viewer_manifest.py and changed my project settings to compile
at release instead of relwithdebinfo. Changed viewer effect beams to be
1.7 seconds. Added some things to settings.xml for the voice lock and
voice hide. removed unresolved external bool in voavatarself in relation
to pose stand.
Removed experimental mvoicevisualizer block, added hud effect send block

Changes to settings.xml include voice toggles no longer being persistent
and defaulting to off.
