Grammar compilation of lexification operator produces error

[stlutz]

Compilation of grammars that use the lexification operator (#) currently produces the following error:
OhmMissingAttributeMethod: LexLex:

Minimal example:

serializedGrammar
^ 'MyGrammar {
	Expression = #Value
}'

This prevents e.g. the compilation of the Javascript Grammar, since it uses lexification operators fairly liberally.
