Remove some whitespace

The licence block contained some whitespace that my
old editor missed to remove. But now thanks to vim
it's gone :)

Fixing bug #1

With the old implementation other developers using the
member model had a problem, because it still contained
the cached values.

Now i am using the member model itself to write the
new value back to the database. So all other extensions
should have the value in the member model as well.
