Moved saved session data from UserConfig to PlayerProfile - which
means that now each player can individually save an online session.
Fixed line endings.
Fixed compiler warnings.

Disable notifications.
Update before_install section in travis config file.
Now each PlayerProfile has a (currently still called) CurrentUser
which manages online connection data. Work-in-progress to use
only one object for all player data (instead of two atm: PlayerProfile
and CurrentUser).
Clean up and re-enable notifications in travis config.
It's even better with the key of the added repository.
