HDLMake version 2.1 promoted to Master

After a huge testing effort, including complex simulations and White Rabbit design synthesis (e.g. WR-NIC), the new HDLMake 2.1 version is out and ready for production-grade use.

The new release supports a load of new synthesis and simulation tools and includes improved features such as custom user code insertion into the whole Manifest.py tree or incremental ISE synthesis in both local and remote hosts.
