Tomas Susanka 445f56d387 core/bitcoin: finalize bitcoin refactor
- core/bitcoin: move common files to the app's root
- core/bitcoin: use require_confirm instead of confirm
- core: move bitcoin unrelated functions from 'bitcoin' to a new 'misc' app
- core/bitcoin: use relative imports inside the app
- core: rename wallet app to bitcoin
- core/wallet: replace SigningErrors and the other exception classes with wire.Errors
