Tentative: power procedures

Currently working power procedures. 
This section is the least tested, due to the work around nature of the prototype hardware. 
Please reevaluate and test when the correct board has been built.

TODO: Please use power pin in new revision, instead of relying exclusively on AT shutdown command (which would fail if there was no communication with the modem).
Also, please confer with original designer about power management (power pin, reset pin, etc)
