Stable 39 - checkpoint

Architectural / checkpoint release - primarily covers refactoring to split out our module system to a separate framework - gestalt-module:

https://github.com/MovingBlocks/gestalt-module

(Why "Gestalt" ? See http://en.wikipedia.org/wiki/Gestalt_psychology - more frameworks will join the Gestalt family over time)

Took a while to get all the actual modules stable again :)
