TransactionURI import & export feature

[yilmazbahadir]

User should be able to export/import a transaction as a TransactionURI (see https://github.com/nemtech/symbol-uri-scheme ).

• TransactionURI Export: On the transfer page, the send button should be changed into a dropdown action button (with preserving the default send button behaviour intact), as an optional action export to TransactionURI should be clicked and URI should be shown on a modal page to copy.

• TransactionURI Import: Can be a modal page being opened by a Top bar menu item or can be another tab to the dashboard transfer tabs

As discussed with @evias, following changes has been applied to the design:

• Instead of modal export transaction URI page, transaction URI is shown on the bottom of the transfer page and it gets updated live as the user fills the details.
• When the user hovers over the link icon a Tooltip is shown and a Poptip is shown for the full version of the transaction URI when user clicks the shortened transaction URI. A copy button for the user to easily copy the transaction URI.

@jabo38 could you also review and share your thoughts on this?

Following are the screenshots of the implementation:

I don't understand why the export transaction URI is on the send screen. In that scenario, I'm guessing the transaction still needs to be signed. So why would somebody take a transaction URI that they haven't signed, then import it into another wallet where they would have to sign it.

I think it makes more sense to put it in the screen where a person has already entered their password and are signing the tx.

So in theory, I would going to the confirm screen, entering my password, but instead of clicking "confirm", I would click on a drop down arrow on the confirm screen that would give the option to export tx as a URI.

And since this is a very advanced feature, but on a page where 99% of people won't be doing something advanced, it would be nice if they were clicking on signed tx as URI, that they were given a way to have an explainer of what they were doing or why they would want to do it.

As for import tx URI, it doesn't look bad where it is in the screen shots and I don't have any suggestions how to improve it.

I think URI Scheme Library doesn't support representing already signed transactions.

Because it says "URI Scheme library to serve Symbol transactions ready to be signed." in the library repo (https://github.com/nemtech/symbol-uri-scheme).
