minor changes to ease debugging/running syncdata:

added logging capabilities by passing -v3
added option to run only specific parts of syncdata --update, by passing --update-run-only=func1,func2,fun3
fix lobbyist translation strings
in member list by presence, sort mk list in python because the db sort acts funny when some values are None, which is the case now, because the new MKs don't have data yet
when filtering committee meetings by date, make sure the committee exists, or raise http404
