Bring back Camera widget option for tablets

Starting from ~2014-01-29, Camera widget is also shown on tablets.
That's actually a good thing, so let's bring back the option to
make it configurable.

Settings: Don't hide home category if user has a settings capable launcher

By default the settings app hides the home category if it notices the user
has 1 launcher. Due to the ability to have settings per launcher, if the
user only has one launcher which happens to support settings, hiding this
category renders that feature useless.

So now we check if the user has < 2 launchers AND whether they support
a settings panel.
