Added Combo System

• When "K" is pressed, it initiates combo mode, in which "J K L" are used to perform a particular combo.
• While in combo mode, "J" does not fire a basic attack and "L" does not reduce incoming damage, which are their normal functions.
• Specific patterns can be input in the array in the inspector in the "Inputs_Lucy_Test" script.
• Currently set to have two combos which don't do anything other than print out text in the console.

Changed Systems

• Changed "press any key to start" to "press space to start" 
• Added a restraint that prevents a player from being able to move around before they start the game by pressing the space key

Bug Fixes

• Fixed a bug where player attacks would collide with the invisible play area boundaries when Lucy was backed all the way up.
