THIS IS A TEST RELEASE.

A small release in view of the Advancing Bitcoin conference, which
brings some fixes as well as the possibility to use Liana as a "hot
wallet".

Features

• Hot keys: users can now generate and sign with keys that are stored on
  the device. It is recommended to be only used for testing for now.

GUI-specific

• It is now possible to use multiple signing device of the same type
  without having to first connect one then the other.

Fixes

• When used as a daemon the lianad process had its PID and logs file
  mixed up. This is now fixed.
• We fixed the transaction creation sanity check that was overestimating
  the transaction fee.

GUI-specific

• In the installer flow, extended keys are now shared without the
  /<0;1>/* suffix.
