Adjusted flip.py tabs
Added Winning, Quitting and Score Tracking

flip.py
;    Modified face-up cards to appear somewhat nicer
(the numbers are easier to read at first glance)
gui_terminal.py
;    Modified ask_question() to be case insensitive
;    Added function to flip all tiles face-up
;    Added "Total_Score" to keep track of scoring
;    Added the option to quit early
(it keeps score, but this isn't immediately apparent to the user)
;    Added "Winning", where the board realizes you've won when you've
reached the max possible score for a board
;    Manipulated strings to look nicer to programmers
