HEVS Update

Updated status code to include HEVS
JSON

Added a file with a first run at a notional JSON object and schema.
Tuner test and script recovery
Tuner control

Tuner control has been implemented. Return of status from the tuner has
not yet been implemented.
Foundation for exec calls

First commits to support movement of Executor calls into Mission Control to prevent them from colliding with Mission Control calls or to alleviate the need for Executor altogether.
JSON object

Switch from dictionary to JSON object. Still not returning it as JSON in
the HTTP response.
Begin tuner debug

Isolate and debug issues with USB control of the tuner
Tuner stabilized

Cleaned up and enhanced the tuner code, but the primary difference in
stability was in shifting from pure USB to a USB-to-Serial plus a null
modem cable.
Prep for merge

Prepare to merge to master
Executor changes

Instead of directly executing scripts passed in from JSON-RPC calls,
Executor now passes those calls to Mission Control for execution.
Mission control updates

Update of Mission Control to handle calls from Executor, exec calls
directly from the socket server, and switch calls from the socket
server. The server will now return pure JSON when called with "/json/"
path.
Prep for merge of executor-redirect

Couple minor things to clean up before merging executor-redirect to
master.

Make server more highly threaded

Add the threading mixin to the socket server to alleviate blocking
issues.
Add MoCoCen and MDDE Directories

Added directories and code covering the MoCoCen and Multi-Display Dev
Environment (MDDE). There will be a subsequent commit for the Single
Display Dev Environment (SDDE).
Reorganize OS1 and update it to current ops code
Add initial version of 2090 Mission Control

This commit adds a complete, but untested version of 2090 that
incorporates the control and status of the projector and receiver in
that room. This should support Elena's web page updates. Integration
will occur in a later commit.
Updates to MoCoCen for installer
