Bring back account filter

- ContactListFilterController no longer loads accounts and groups,
to display in the action bar drop down menu. Now it just stores
current filter and saves it to preferences.
- ContactListFilterLoader is no longer needed because we're not
loading groups anymore
- Move adapter from ContactListFilterController to the
AccountFilterActivity
- AccountFilterActivity loads a list of accounts and returns
a ContactListFilter as an activity result based on the account
selected
- If "customize" is selected, then the CustomContactListFilterActivity
will be launched.
- Show header in contacts list according to what account filter
was selected
- Update filter activities to holo theme

- TODO: Remove the "display phones only" option in the
customize menu on the phone
