Add `goto vob` and `goto camera` marvin commands

[thokkat]

goto vob teleports the player to a vob that matches the given name. A index number can be added to teleport to the n_th vob in case there exist multiple, often the case for items. Only npcs and items are tested for now but in vanilla it works for all kind of vobs.

goto camera teleports the player to the camera position. I found this came in handy when I wanted to observe a npc without percs being triggered but then move quickly to the scene to look what would happen.
