Node Hue Api Versions Save

• Adding more information from lights() and getLights() to include details on the light type, model, id and software version
• Updated documentation for LightState

• Massive refactoring of LightState which is a breaking change from version 0.2.7
• LightState convenience functions to support simpler creation of new states
• Modified the way that RGB is converted to an XY value for light state objects
• Removed deprecated HueApi.connect() function
• Added more convenience functions to HueApi to provide multiple language options and make functions consistent (e.g. lightState() and getLightState())
• Added scene API support
• Updated HTTP request library to 2.51.0
• Added timezone retrieval from the bridge
• Greatly increased test case coverage

• Added functions nupnpSearch and upnpSearch for bridge discovery and deprecated old search function references
• Updated the Groups API and documentation to support latest Hue Bridge software version
• LightGroup 0 name now provided from the bridge, rather than called All Lights
• Provided separate functions for the different types of groups that are now possible in Bridge API version 1.4+
• Added advanced option to specify the port number for the bridge
• Added convenience getVersion function to obtain software and API versions of the bridge

• Fixes a bug introduced in 0.2.5 that would modify the LightState object if you have an rgb value set, making the state object unusable to multiple calls to different lights.

Fixes for RGB conversion into XY co-ordinates for lamps to give better accuracy compared to previous implementation using HSL

• Fixing endpoint for meethue to support https
• Replacing q-io with request backed library for http(s) connections
