Installer

-Modifies man.cpp to get player and team numbers from a .json parameter file rather than from including a header which defines them. This means that libman.so does not have to be recompiled if just the player number or team number has changed.
-Creates an installer tool which allows the user to specify parameters for up to 5 players at once and then install them by clicking a button

Benefits of this: 
~The user can set up a team all at once before installing rather than alternating between `make cross` and `make install`
~Reduces risk of error by checking for a valid python player, agreement between player number & pGoalie etc.
