Fixed issue #46 with a dirty dirty hack. Messed with the z-index of the ...

...hal pop up so it allows the other popup priority. We could also (if we didnt want the pop up to be there at all) make the hal popup z index go negative or 0 when the other slider pops up. But we might risk HALs popup being up but not visible during some intermediate stage of the other popups so that we'd have the endgame popup hidden but hals was still up. effectively killing user interaction. so maybe we shouldnt do that. Plus, HALs so cute glowing over there
