Welcome autocomplete for player names

Now it's possible to add new simulations by player name like:

ccs> demarchi wins-against lfelipe
ccs> lfelipe wins-against noob
ccs> noob loses-against ulisses
Welcome colored simulations

Refactor to use a proper Games class so we can mark each game if it's
simulated then add color for those when printing the table. The method
to print the table is a bit convoluted because we can't use the format
fnction in python to centralize the string if colors are enabled because
it doesn't discard the escape terminar characters
