RoboSats v0.5.1 is now out! :rocket:

## Changes:
- API requests to POST /order that contain important information, i.e, the payout invoice or address, are now signed by the robot PGP key and validated by the coordinator. This way, on a multi coordinator set up, a robot can potentially be re-used across several coordinators without risk of identity stealing (auth token) by a rogue coordinator (alla man-in-the-middle).
- New maker form switch for exact and range amounts by @JooVLC
- Fix negative premium field by @JooVLC
- Self-hosted node app has been fully re-worked. It is now based on Alpine (size went down from 130MB to 7MB) and the ram-heavy dependencies have been dropped. The app is now lighter to run and fully self-contained.

### Verify the app using GPG:

1. [Download the ascii armored signature](https://github.com/Reckless-Satoshi/robosats/releases/download/v0.5.1-alpha/robosats-v0.5.1.alpha-universal.apk.asc)

2. Run this command on a directory that contains the apk file and and the ascii armored signature.
`gpg --verify robosats-v0.5.1.alpha-universal.apk.asc`

3. Verify the signer is actually Reckless-Satoshi (fingerprints match): [B4AB5F19113D4125DDF217739C4585B561315571](https://keys.openpgp.org/vks/v1/by-fingerprint/B4AB5F19113D4125DDF217739C4585B561315571)

Alternatively you can also verify with the release with the SHA256 checksum.

Known missing features:
- Android APK has no sound or notifications.
