[Chrome Extension] AI2Helper - download all blocks seperately and remove all orphan blocks with one click

[Kevinkun]

@Kevinkun

I made another version of AI2 block helper:

I made an update for this AI2HELPER， now it looks like this:

Click the AI2HELPER button, it will show (or hide) a palette, you will see some buttons and a list of all the top blocks (global variables, procedures, and events) in alphabetical order.

Click on this list item, it will highlight the relavent blocks.
