Insteon/X10: Skip Calling Set_Receive on PLM

Not clear on what this does for a general X10 interface, but the Insteon PLM has no state, therefore it has no set_receive command.  The safest thing to do is just to skip this call for Insteon PLMs.

Nest: First Draft of Nest Support

- Adds read-only support for Nest Thermostats
- Very little documentation
Nest: Move Get_Value into Nest_Child

This will make it usable on both structures and smoke detectors

Change device_id so it checks the name of parent, unlikely that device-children will need to get their IDs but this way it will work as expected.
Nest: Add Support for Smoke/CO Alarm

- Still very little documentation
Nest: Add Support for Structures
Nest: Add Base Function for Sending Data to Nest

Rearrange url and auth parameters

PushBullet: Fix Bug in Reading Token from ini; Fix example; Fix Error Message

It looks like Pushbullet changed the structure of the JSON for error messages.  This should now cause them to be printed for diagnostic purposes.

Fix Link Generation in Items and Modules Documenation Pages

I don't know when or how this broke, but I made some changes to update_docs some months back.

I noticed that on my local copy, the links on the Items and Modules pages were non-existant.  This change fixes that.

I also made a change to the pod.css so that CODE tags are mono-spaced formatted.
Nest: Add Auth Ini Parameter; Reorganize Connect_Stream
Nest: Change from Passing a Scalar to a Code Ref

Eval is heavily frowned upon.  It is hard to create a nice scalar command, plus the error messages are often unhelpful.

Using Code References is much easier and possibly allows for greater functionality as it can run on non-global objects.
