Created block for colorLeds[i].pulse

[MeyAyre]

Added this ability to the johnny-five RGB component in code-dot-org/johnny-five#10. This PR updates the johnny-five version to one with the new feature, and adds maker blocks so it's available to students and levelbuilders.

Pulse looks really nice in the video!

Would we want to add this to sharedApplabBlocks.js ? I see most other maker commands there, and my reading of

code-dot-org/apps/src/applab/levels.js

Lines 37 to 42 in 3339b35

	* This is the default set of functions available to us if the levelbuilder
	* leaves codeFunctions blank.
	* They are defined in Applab.rb, and generated into a static JS file via
	* generateSharedConstants.rb
	*/
	'codeFunctions': ApplabBlocks

is that this would be needed to make this block available to levelbuilders.

LGTM after considering adding to sharedApplabBlocks.js.

Including this block in shared_constants.rb is sufficient; from the top of sharedApplabBlocks.js:

// This is a generated file and SHOULD NOT BE EDITTED MANUALLY!!
// Contents are generated as part of grunt build
// Source of truth is lib/cdo/shared_constants.rb

Ah right, plus sharedApplabBlocks.js is not even in our repo. sounds good :-)
