Extensión Bookmarks Import & Export

[NOTE] Opera now includes the ability to export and import bookmarks,
so this extension is no longer necessary, and will not be maintained.

This extension allows you to backup & share bookmarks with Chrome,
Opera, Opera Classic, Firefox, Vivaldi and most other modern browsers.

Import & Export will export everything including "Speed Dial" & "Bookmarks Bar",
as it's using a documented bookmarks API called "chrome.bookmarks.getTree".

There were some comments that "Speed Dial" was not exported,- that's not true,
it will be exported but could be re-named,- this depends on the Opera version.
If you have folders inside folders, they will be moved to the "root" folder.

When importing, it will import to a new folder called "Imported Bookmarks",
which can then be managed as desired. One can verify the number of items
that were imported / exported, by reading the item count after an import / export.
