Stefan Thomas 05f3a97042 UInt160 can be an account or a plain hash. 
The UInt160 class used to be hardcoded to be an Account. This commit changes it
so it can be used as an account or a plain hash. It will try to automatically
self-classify based on how it is initialized.

In the future we may want to have some dedicated classes rather than a
single configurable UInt160.
