Added 4 includes to allow for compilation on modern Ubuntu versions

Release v1.2.1

Added Windows X64 binary and hash_algo.txt

Production Release v1.1.1

Fixes a bug in the hash algorithm that causes nodes to crash when validating blocks generated for said algorithm. You must update your nodes with this release, or at least copy hash_algo.txt into the dir where you run your nodes.

Production release 1.0

Tagging for virtual machine development. Anything after this tag is development work for v2.0.
