config: add LightBlue Bean board definition and docs

[mplewis]

This pull request adds support for compiling Arduino sketches for the LightBlue Bean.

Not yet ready to merge. I still need to add Bean libraries to this pull request, but I'm not sure how.

I have gotten sketches for Bean to compile locally by adding the following files to ~/.platformio. This pull request already takes care of the board definition file punchthrough.json, but I'm not sure what to do about cores/bean or variants/bean.

@ivankravets, can you help me figure out where I can place the following files?

Thanks a lot for the request 👍

1. Please remove "doc" files from pull-request and just leave platformio/boards/punchthrough.json. Docs will be generated automatically.
2. Please archive mentioned files and give me a link to archive. We will put these files to framework-arduinoavr package.

[mplewis]

OK, I've removed the changes to the doc files.

The Bean libraries for PlatformIO are available here: lightblue-bean-platformio.zip.

Please let me know if you need anything else. Thanks!

@valeros could I ask you to repack and reupload framework-arduinoavr with these files? Thanks!
