implement member management system

[rafd]

My notes from long ago:
Member Role Management
groups w/ 1 member = role (ex. pres)
groups can be given arbitrary properties
ex. description, email, website

    interface:
        left column: 
            nested list of subgroups and members
            r-click to edit group properties
            click to edit name
            click-drag to move (change order)
            + icon to right of each group name, adds new group
        right column:
            list of group members
            at top: search for specific member
        actions:
            drag/drop members into roles
