This changes extends SLICC to understand two different kinds of slicc files: files that are protocol-specific and files that are shared or included between different protocols. Each declaration in SLICC can now be shared or not. If it is shared, then we can take a different action in the code generation (e.g., wrap in a namespace). *Developer facing change* Removes the RubySlicc_interfaces.slicc file from the SLICC includes of every protocol. Changes required: If you have a custom protocol, you will need to remove the line `include "RubySlicc_interfaces.slicc" from your .slicc file.
