Make default timeout project dependent

[xicodomingues]

Change it instead of having only one global timeout that is predefined for all projects, make the timeout dependent on the project

For example:
libft - 3
get_net_line - 15

(And think about which are the good ones for every project)

As far as I know, 42 system uses 10s by default. But some cases like gnl your 42 is less exigent than your test (I think). Thanks Paco!
