Feature/inventory to master

[K-Mistele]

1. Adds a dynamic inventory system:
   • list of discovered inventory items stored in player_inventory
   • each item is a dictionary (may later convert so an object from an item class),
     • each item has quantity, name (used for player inventory command), duration, item ID, and effect
     • the effect attribute should be a function defined PRIOR TO defining the item in adventure.py
   • speed potion item created, more to come
2. Compared to origin, adds a new movement system based on key events.
   • installed a module to local_modules calledkeyboard and imported into adventure.py
     • listens for key events, no "enter" needed for movement commands for opening inventory
   • reworked movement system to be compatible with speed function
3. New class generation system for game tiles, will later use to be able to generate multiple tiles
   • procedurally generates forest ^ and mountain M and lake . tiles
     • no two maps are the same (unless you get astronomically unlucky)
   • adds map borders (#) that you cannot cross
4. Finally untracked that pesky .idea/workspace.xml file by adding to .gitignore
