Additional spectator fixes

- fixed issues with piemenu cursor code being enabled when spectating
- the cursor is now enabled when in an observer mode that locks the view.
- fixed bugs/exploits where dead players could first person spectate the enemy team or travel around in freelook if all spectatable players on the team are dead.
