Wave Extensions Gallery integration

A little over a month ago, I announced the first release of the Wave Extensions Gallery search API (wavygallery.appspot.com/docs/api/v0/search). Not long after that, I released the WEG Loader for Rizzoma Chrome extension, which used the WEG search API to put WEG gadgets in Rizzoma's gadgets menu. It would be great to see WEG gadgets also be searchable from the WIAB gadgets dialog.

WIAB already has a gadget searching UI. It would require essentially no UI changes to implement this. All that would change is what happens with the search query behind the scenes. Instead of searching within a hard-coded JSON file, send a request to the WEG search API and parse the JSON response.

The advantages of using the WEG API over the current method are a) the gadget URLs, icons, and metadata will always be up-to-date, and b) WIAB instances will not all need to store their own hard-coded gadget lists.
