(#2360) - PouchDB.defaults() missing some fields
bulkdocs response may not contain .ok property

I hit this case when syncing against Sync Gateway.
(#2358) - multiple attachments correctly replicate
(#2370) - update pygments to highlighter
(#2372) - update adapters.md for safari/ios

Let's spread the good word - Safari and iOS
will have IndexedDB. :)
(#2382) - test performance in node
(#2387) - document CORS error
(#2023) - don't save revisions of local docs
(#2342) - add tests for update_seq

This test reproduces the error reported in #2342.
Before the fix, it succeeds in the http-http and
http-local tests but fails in the other 2 combinations.
After the fix, it passes all four.
(#2375) - Simplify the less of the logo
(#2376) - clean up external.md
(pouchdb/mapreduce#191) - add migration test
