Feature Request: Variables

[bradhawkins85]

Need the ability to store variables against Clients/Sites/Devices and Globally which can then be used later in tasks and checks.
It would be good if these variables could be updated via tasks or checks too.
E.G. Store a software product key for a client such as #antiviruskey# and then can use this in script arguments like c:\windows\temp\myinstaller.exe #antiviruskey#
