Proposal to add Android App Widget

Joplin knows what type of resource (note, notebook, tag) the id is anyway, so we don’t really need to specify the type in the URI. We can, but it’s not necessary. Unless we want different behavior between:

joplin://NOTEHASH
joplin://note/NOTEHASH

But I’m not sure what different actions we could choose. On the other side we can always do something like this in the future:

joplin://HASH[/action]
