Subscription Support for Mobile

[ohager]

Is your feature request related to a problem? Please describe. Beside the ordinary and multi-out transactions, Phoenix should also support the handling of subscriptions. The subscriptions is a unique feature of the Burstchain and can be used as a replacment of standing order for a bank account. Also with a deeplink functionality ppl could start paying in an given intervall to organisation they like to support ( like greenpeace)

Describe the solution you'd like The supported features should be within Phoenix as screens:

• Adding a subscription
• Delete/stop a subscription
• Subscription Overview

For adding a subscription the user should be able to add the intervall in terms of hours, days, months or years (h,d,m,y) like 3d - and the script is converting the intervall into seconds as needed.

Also in the Overview the intervall should be shown in user readable terms instead of seconds ( like in the current BRS)

Additional context It should be possible to add and/or delete/stop subscription via deeplink. SignumJS should have the functionality for subscription already.
