- fixed : LLPipeline::sShowHUDAttachments isn't reset to TRUE when an attachment is worn on an empty RLV_LOCK_REMOVE locked HUD attachment point
    -> @remattach:top=n (with no current attachment on "top" or any other locked HUD attachments)
    -> uncheck "Show HUD Attachments" (allowed because RlvAttachmentLocks::hasLockedHUD() will return FALSE when there are no locked HUDs)
    -> attach HUD attachment to top => invisible
- fixed : HUD zoom level should be restricted when a HUD attachment is non-detachable
- fixed : wireframe should be disabled when a HUD attachment is non-detachable
