User friendly toast error message store

[JonRay15]

The Chore

Build some sort of table that simple stores a user friendly error description against all Core errors that come back.

Whenever we get a core error we should check against this store to see if we have a user friendly message and if so display it. If we dont have one then fall back on the technical error direct from Core.

Known errors

• [ ] Large withdrawal is not old enough >> "The withdrawal cannot be completed until the withdrawal delay has finished"
• [ ]
