The initial design has done well for over 2 years, but problems
are starting to show.
This does a bit of cleanup in the UX and many cleanups in the
underlying architecture that were the result of those UX choices.
We remove the clipboard (paste) concept from the camera pipeline
completely and simply make it a new top-level button "paste" on the
send page. This helps discovery AND helps architecture!
The both workflows now also become 2 stage affairs, when the button
is pressed we open a page that does the scanning or pasting and then
introspects the actual data in order to redirect to the right page.
This means that we auto-detect if the scanned item is an address or
a private key or whatever, and handle it appropriately without needing
any user interaction.
