Bestiary, Loot and UI changes incoming!

Here we go:

• added some more informational texts for new players that will help learn the game (e.g. "use the torch in your first hotslot to make light"). - Buff Info now has an "OK" button so that you won't cancel it by accident. - Added day and night cycle to the overworld. - Added Defense Potion. - Adjusted the Grimoire: you will now learn the spell even if you can't cast it yet. - New: The bestiary keeps track of your kills. Access it from your character screen, Icon in the upper right. Bonus: the more creatures of a certain type you kill, the better your chance of landing a critical hit in the future. - Changed the loot mechanism. You can now buy silver keys. Silver chests may contain a gold key (also dropped by creatures). On every 5 levels of a dungeon there is a golden chest which requires a gold key. Gold chest loot is better than silver chest loot. You may find a platinum key in a gold chest. Platinum keys open Platinum Chests that can be found on every 5 levels of a HARD MODE dungeon. Platinum Chests contain unique magic items. - Combining items now takes time. - Added Elite enemies (to HARD MODE dungeons). - Added background pictures to the level loading screen. - Changed the UI (colors and fonts) so that it won't hurt your eyes any longer ;-) - Added AE damage to "Shatter". - A Scythe is now required to summon a reaper pet. - You can now load/save during Work (Mining). - New Mining progression screen. - Saving is now enabled in the royal mines. - Saving is now disabled in hard mode dungeons. - You can now cast spells from out of your character screen. - Skill reset now costs gold. - Many other fixes to known errors.
