[Beta] 2016.01.23: Hero Portals — Tomb of Tyrants Steam update #991335

http://i.imgur.com/f523XiZ.png Due to the beta's more coherent and condensed UI and controls, I am knee-deep in controller support implementation, so this update is mostly minor additions, changes, and fixes to keep the beta going until the next big component is ready. The most significant addition here is that fortified checkpoints gain portals that allow new heroes to spawn within your dungeon (these spawns come from the same wave pool as those on the surface). Thank you for your continued feedback on the beta; I am seeing a few comments that run contrary to my expectations, and that's a big part of why I beta these major changes first. I'll see what I can do to keep the game feeling fresh and fun for as many of you as possible! Remember, if you are interested in trying out the beta, you can opt-in from the game's properties menu in your Steam library. Thanks again :totcordial:! Change...
