fix(amazon): Fix Amazon metadata search

[jgoguen]

Amazon search for metadata has been returning HTTP 503. This appears to fix that for amazon.com. Also makes some changes to the attributes searched for to accommodate Amazon changes.

This may fix #701

Hello,

thank you for the fix. I've tested it and it works, somehow.

I didn't get any ratings.

I've hardcoded the rating for testing:

                    try:
                        match.rating = 3
                    except (AttributeError, ValueError):
                        match.rating = 0
                    try:

but still no rating.

I checked the rating fetch and it did need updating I pushed a new commit with that and a couple other fixes, but it still isn't in the UI. Checking with log.debug(match.rating) shows it's being set correctly, could it be something isn't making it to the UI or isn't being used?

Looking at cps/templates/book_edit.html it looks like this is where the modal dialog is defined, but I don't see anything that would show the rating.

[redskull1986]

I found in cps/static/js/get_meta.js

// Removed as users can't fetch ratings from metadata providers // $("#rating").data("rating").setValue(Math.round(book.rating));

I don't know, when it was changed.

If I uncomment it. CWA don't display the rating, but it save it.

[jgoguen]

It might be better to do the UI all in a separate PR then. I know I don't save the rating from metadata fetching, I wouldn't want it to be enabled without any way to disable it.
