As mentioned in #17 arrow keys did not work as valid configurations, this pull request fixes that problem
Arrow keys are entered as
"up" - Up arrow key
"right" - Right arrow key
"down" - Down arrow key
"left" - left arrow key.
The program keeps the check to make sure it is either a valid arrow key, or a single charachter,
the display message for incorrect inputs has been updated aswell.
