Initial setup of tracking percepts
Refactored all 'capleft' to 'ecapleft', case dependent of function of statement (variable or not)
Car position and capacity left are now correctly saved, and sent to the manager in form elevatorState(Position, Direction, CapacityLeft)
A call from a floor is now sent to the manager in the form 'buttonCall(Level,Dir)' to prevent confusion with the percept
Tidied up the percept handling, categorised actions and cleaned up mailbox
Lined out comment section headers
Lined out comment section headers, part II
Merge pull request #3 from tomrunia/car-to-manager-comm

Manager now works in order to handle new messages.
