Ability to set custom nickname for payee's addresses

[peasandwell]

In some circumstances there will be situations where there may be many incoming payments from unregistered addresses, however the problem is that the addresses are not human friendly which can lead to confusion.

A good improvement could be that the vendor has the ability to add a custom nickname to a particular address (maybe by tapping on the address in the payments screen).

Note that this may require the need for some form of local storage so that all the user's settings aren't lost when the page is refreshed.

Also planning really far ahead - we should allow them to export the localstorage-stored identities and re-import them on a new device when the device is changed. I guess just base64 encoded JSON

OK, added to the Sketch Prototype https://sketch.cloud/s/aMlnp/all/onboarding/start-page/play

More features in here than were actually requested, because I like unrequested scope creep!

Features are:

• Can select any transaction item from the list to open the 'Payee Profile' panel
• Payee Profile allows specification of a Nickname as well as a photo (triggering iPad Camera)
• Transaction History will be available from here too so we can check if that payee did make a payment on specific days.

Also, the Settings panel itself now has a new link to view Payee Nicknames (might change this to 'Payee Profiles') that triggers a list of all the custom payees.
