Deprecation warning indexedDB.webkitGetDatabaseNames()

[hadrien-toma]

This issue is for noticing a deprecation warning using pouchdb-all-dbs:

eval.js:42 [Deprecation] indexedDB.webkitGetDatabaseNames() is deprecated and will be removed in M60, around August 2017. See https://www.chromestatus.com/features/5725741740195840 for more details.

I am using version 1.0.2.
I wish these changes are not too impacting...

That's actually not a pouchdb-all-dbs bug, but one for the PouchDB chrome extension. Unless there's an alternative API provided for extensions (for listing all the indexeddb databases, and I expect not), it will be impossible to fix.

I guess it might be possible to ask the user which database to inspect, this would also fix the firefox addon that broke a while ago for similar reasons. But, to be honest, I currently don't have the time to look into that. If someone else wants to, feel free to open a PR and ping me, then I'll merge + publish it to the chrome store.
