Small Update 1

Wasn't expecting to find the time to do this but here we are. Next update is gonna be the big one and it's also gonna take a while.

• Added artwork which was generously donated by Cesardrake.
• Added an INT training method, Nyxi is the current trainer and helping planty also gives some INT exp once.
• In the spirit of working out the perks and new skills system I've added a new INT based skill which is acquired by having an INT score of 6 and an STR perk which is acquired by having an STR score 6.
• Messed around with the growth numbers a little bit. FMG is a little faster now.
• Fixed the cup sizes displaying incorrectly and making BE extremely fast.
• Fixed the INT stat indicator on the sidebar which was actually displaying the dex value instead.
• Fixed an issue where finding loot in a dungeon had an 1/10 chance to give nothing.
