Subject: Adding dynamic ossl permission control

Add permission by identifying uuid (owner/creator/group) and function. Revoke
permission in the same manner. Permission adjustments immediately effect
running scripts ability to call os functions.

osGrantScriptPermissions(UUID key,string function) Threat Level Severe
osRevokeScriptPermissions(UUID key,string function) Threat Level Severe
