mem-ruby: Allow SLICC symbols to have no description.
Updated the SLICC `Symbol` class to return an empty string when its
`desc` property is read.
The SLICC language does not require a symbol to have a `desc` for
protocol generation, but the generation of SLICC HTML documentation
expects a `desc` and will fail if it is not present.
