Introducing Damus Notedeck: a nostr browser

This splits notedeck into:

- notedeck
- notedeck_chrome
- notedeck_columns

The `notedeck` crate is the library that `notedeck_chrome` and
`notedeck_columns`, use. It contains common functionality related to
notedeck apps such as the NoteCache, ImageCache, etc.

The `notedeck_chrome` crate is the binary and ui chrome. It is
responsible for managing themes, user accounts, signing, data paths,
nostrdb, image caches etc. It will eventually have its own ui which has
yet to be determined.  For now it just manages the browser data, which
is passed to apps via a new struct called `AppContext`.

`notedeck_columns` is our columns app, with less responsibility now that
more things are handled by `notedeck_chrome`

There is still much work left to do before this is a proper browser:

- process isolation
- sandboxing
- etc

This is the beginning of a new era! We're just getting started.
