Major API overall
Updated information on configuration

We need to add a separate doc describing the settings for config.
Small docs update
Updated models with svmp object
Added CLI option to erase sessions

Added "clear-session-info" CLI option to erase all sessions for a
given user.
API overhaul bugfixes

Tested proxy, fixed various object reference issues.
Added config file README

The config file is now JSON, so it can't have normal JavaScript
comments. Instead, created this file to describe the various
configuration values that are available for the server.
Added unit test for sessions

Updated authentication-test file to include a working unit test
for session re-authentication.
Updated README to show how to install and use Grunt for unit tests.
small changes while working on benchmarks
Added simple benchmarks
Updated config file README

Added more description for the "new_vm_defaults":"images" setting.
Improving/fixing openstack

Also added table output for cli
testing notes
Small bugfixes

Fixed config, now correctly constructs VideoResponse JSON to
avoid causing svmpd to crash.
Fixed proxy, now correctly forwards raw message from VMSocket
instead of trying to construct it into a Response.
Updated protocol debug logging.
More bugfixes

Fixed svmpsocket, added missing destroy() function.
Fixed server, added missing printErr() function.
Fixed proxy, changed VIDEO_PARAMS message to get sent to the client
instead of the VM.
Added debug logging for requests/responses when in the PROXYREADY
state.
Merge branch 'refactor'

Complete refactor of the code base

- Broke areas of responsibility into smaller components
- Created PacketReader and Custom socket reader/writer to support
  the delimited SVMP protocol
- All core functionality is instantiated automatically by calling
  svmp.init()
- The module space "svmp" is available throughout the frameworks 
  for core components. For example, to use openstack, you can call
  svmp.openstack, etc...
- Moved configuration to a more flexible API building on an existing
  opensource library. Settings can be modified at runtime. via
  "svmp.config.get()/set()" See tests for and example.
- Created repeatable tests for most core functionality
- Added enhancements to CLI such as table formatting on the 
  commandline

Conflicts:

* b2c67fd Add ICE server username & password fields to config schema
	config/config-local.js.example
	config/schema.js

  Example config changes copied over from now-removed config-local.js.example
  to the new config-local-example.json.

  Schema diffs changes to match new code style.

* abd0fb7 Changed proxy Response handling
	lib/proxy.js

  Changes made obsolete since the refactoring completely replaced the protobuf
  socket handling and message parsing.
