Game speed, new UI scheme and more...

Game speed enhanced a lot on outer world (approx. 50% faster)
New UI color scheme - Dark Brown
I finally launched a Discord server: https://discord.gg/Rbaa4cHtzM


Changes from players feedback:
- old lines in the discuss dialog drawn with a little transparency
- some hints to game mechanics added
- arrows and knives have separate images when broken
- button "Show on the World Map" added on the quest list item
