Use array for arguments at m\question->writeOut()

writeOut(true, true) becomes writeOut(['extended', 'partial'])
It is more self-documenting
Improved error handling at c\fblogin

facebooklogin() prints errorMessage() on exception catch
disconnectFb() redirects to settings with a message on error
Rewrote m\LoadQ::main()

Removed useless try{}
Make use of m\QuestionSet
Do not writeOut(), leave it for the views/controllers
Updated profile, api@load to new m\LoadQ
Minor improvements

Removed useless 'use' statements
At m\User, added private influencedBy(), called by profileVisibleBy()
and askableBy()
