Re-add more stashes into the prison

Adding more stashes back into the prison, we lost at least 10-14 when the prison was remade.

Having the amount of stashes we had before, it made for a variety of RP for DoC and inmates/Lifers, and gave us more places to hide things, plus 2 of the old stashes (and one of the current) required a screwdriver to access, giving them more use than just a shank. We dont have to go back to having that many stashes, but adding a few more into various places would add some variety back and help with InmateRP

I'm not fussy about where they get added, but I did like the idea of the stash in the old pool table and the plant.
