[watch only] Watch only transaction

closes #1682

I need to rebase, so if can test in trezor mode, that would be great.

Only small issue is that in trezor-enabled wallets, you shouldn't show the unsigned transaction, but rather continue with the signing flow (which should send the sign request to trezor).

You can manually set a wallet as using trezor (to test out the behavior, even if you can't sign it) by modifying the wallet's config.json (not the global one) to have trezor: true.

One thing I noticed, is that when in trezor mode, the wallet seems to not turn it off, when switching between wallets.

Yeah, I had noticed that bug earlier in regards to the sidebar. Fixed in #1876.

One last nit: transactions can be big and overflow the white area (eg):

Thanks! This will be nice to have!
