create, update, delete clients

[adamrneary]

• create here: http://localhost:9000/index.html#/1/clients

if you are logged in as "sound advice" and you create a client, company id should be sound advice's company id (so it should show in the client list!)

• edit name by double-clicking the name once selected: http://cl.ly/image/3B053O3g1X3E
• you cannot delete clients, but you can mark them archived form the client list. this includes a prompt to confirm
• we need to add "Active" and "Archived" words at the bottom of the client list like the "complete" and "incomplete" text at the bottom of the ember getting started example. active shows by default, but we should be able to display archived clients by clicking "archived"
• from the archived clients list, we should be able to restore a client from the table using a restore button
