Switch localStorage with localForage

[Aradiv]

currently we are using localStorage extensivly.

But localStorage has multiple downsites that slow down iitc.

• can only store strings so we are constantly converting data from and to String
• is synchronos so we always have to wait till the read/write is done
• when we have a lot data and we only change a portion of it we have to rewrite the entire string
• it doenst have scopes so we are trying to simulate this with keys like "iitc-bookmarks-portals"

With localForage there is a lightweight and easy to use libary that allows to easily switch to indexdb/websql (if available and will fallback to localStorage if not)

@Aradiv localForage looks promising. Are there some other alternatives to choose from?

https://developers.google.com/web/fundamentals/instant-and-offline/web-storage/offline-for-pwa (or https://developers.google.com/web/ilt/pwa/working-with-indexeddb) recommends idb: https://github.com/jakearchibald/idb#readme (or https://github.com/jakearchibald/idb-keyval#readme)

And there are many similar:

• https://dexie.org/
• https://jsstore.net/

• ...

And I like https://pouchdb.com/ 'cause it syncs. But again, there are alternatives, e.g. https://kintojs.readthedocs.io/en/latest
