Feature Request: Support Tag Groupings for Area Cards

[polskikrol]

What if there are lights I dont want to include for an Area Card? What is there are switches I dont want to include for an Area Card? What if I want TWO sets of switchs with different names?

A feature would be to use a filter/tags to display certain entities within an Area Card for control/toggling. Additionally, the ability to add additional icons/toggls for different Area things. A zwave switch may control a dehumidifier. A zwave switch may control xmas tree lights or maybe a bug zapper.
