This PR is not required for the other sprint 37 live preview bugs.

I think this is low priority, since it doesn't solve any current bugs. Does that seem reasonable?

[redmunds]

@jasonsanjose Sorry for letting this languish. I thought we wouldn't be needing it with new Live Preview, but I'm not sure if that's true. Is this PR still good to merge?

[redmunds]

Merging.

Inspector.html needs to be re-generated for the updated API. @jdiehl Do you happen to remember which tools, templates, transforms, etc. that you used to generate this file?

[jdiehl]

The script is included in the repository: Simply run ruby jsdoc.rb in brackets/src/LiveDevelopment/Inspect. This will overwrite Inspector.html with the updated documentation.

@jdiehl Cool, thx! Apparently, the name of that script was not obvious enough for me :)
