Hooks and feedback now operational! The engine and gui are now
seperate but integrated! Now on to the real stuffs. The instructions
page will stay a placeholder for now.
PlayerPane now more or less constructed;
need to make more pretty, but that can come
later. Still need to connect the engine to
PlayerPane, and make the instances of
PlayerPane in GamePage to be member
variables.
Stuff happened; had to rename iconnect4gui.
this is messing stuff up on git, though, so re-
Added virtual functions to IConnect4. Everything works right now. Next,
to create the gameboard.
