nip19: use bech32 npub and note in uris

convert pubkey to npub and event id to note and store for
later. use npub and note for uri's so that we dont need to
guess what the view of a specific uri has to render.

this is only the first step that changes uri's, next step is
for the view to react to npub or note and render the
correct view accordingly.
