Added emergency map backup system (EMBS). When the editor crashes, it will try to export a backup copy of the map structures. When the same map is loaded again, it will ask the user if he wants to restore the map.
High-DPI: fixed many issues with incorrect controls size (Tag selector width, Comment Editor size, icons size, tabs size etc.).
Cosmetic: changed map geometry dragging undo messages to more descriptive ones.
Fixed, Textures Browser, cosmetic: "Show textures in subdirectories" checkbox should be repositioned when "Long texture names" one is invisible.
Updated ZDoom_DECORATE.cfg (added A_SetFloatSpeed + a couple of fixes).
