Connection to Server NEEDS a profile

Handle the fact that the user wants to connect to a server but he hasn't create a profile or set a default profile.

The check can be reduce to check if the availableProfiles list is not empty ;)
(If the User doesn't set a default profile, the first of availableProfiles is set as default Profile)

Everything is allright for the test !

JUST ONE THING : concerning the idDefaultProfile, it doesn't put the int to -1 when there is no more profile.

Otherwise, I've already coded the test & intent to create/edit a profile if the connection cannot be effective.

I'm juste waiting for your modification on TouchIRC
