v0.11.1

Full Changelog: v0.10.0...v0.11.1

v0.10.0

Charms v0.10.0 brings native coins visibility to app contracts. Combined with Scrolls this enables smart contracts on Bitcoin that can lock and unlock BTC.

This release also completes the ground work necessary for Charms being represented on Cardano as CNTs.

Also, Charms can now be securely beamed from Bitcoin to... currently only Bitcoin (but also any other chains, when we add support for them). Great news is: now adding support for Bitcoin clones is straightforward, so now Litecoin and Dogecoin can be added almost trivially.

What's Changed

• Native coin handling in spells by @imikushin in #127
• Prepare v0.10 release by @imikushin in #133
