Patch 1.53 — In My Defense Steam update #97650

Removed number of flares from HUD when playing endless wave mode. Removed Wood Guardian power-up from list of potential power-up for the mystery power-up. Before this change, if Wood Guardian power-up was selected, when mystery power-up was activated, nothing would happen due to the special processing involved with the Wood Guardian power-up. Added stalagmites to the foreground plant pool.
