Provide detailed versioning and change logs of Mark II OS and it's components

[krisgesling]

The software running a Mycroft device can be considered a whole, however it is also made up of a large number of component technologies. Each layer and component of the stack should be appropriately versioned and provide a change log when updated. Change logs of any child technologies should be collated and referenced in the parents change log.

This includes the following levels:

• Mark II OS - a complete packaged image as is downloaded by end-users.
  • Containers - Pantacor containers that can be updated independently.
    • BSP container
    • awconnect container
    • Mycroft container - this can be modified independently of it's components.
      This is the current build timestamp shown on the homescreen.
      • Mycroft-core
      • Mycroft-GUI
      • Mycroft-gui-mark-2
      • Mycroft Skills
      • Other Mycroft components - eg Adapt, Padatious, Mimic, etc
        These I believe are all versioned appropriately.
