Fixes several bugs from v0.1.10.

If it something breaks, please report the bug and then downgrade to v0.1.9.

I only built binaries for Linux and macOS, let me know if you need anything else.

Use at your own risk:

1. The code is still under development, it's had much less review than the regular Bitcoin Core releases. See #68
2. The binaries were generated by me. It's safer to compile yourself from the sv2 branch here, which will also give you the most recent version.

For macOS: the binaries are not code-signed. On Apple Silicon you need to do codesign -s - bitcoind. On Intel mac you can instead open it once by right-clicking on the file, after that starting from the command-line should work. The zip file contains the GUI, whereas the tar file contains bitcoind and bitcoin-cli.
