* generator/*.cs : Move into GtkSharp.Generation namespace.
	* generator/CodeGenerator.cs (Main): Add usage check. Add SymbolTable.
	* generator/EnumGen.cs (QualifiedName): New.
	(Generate): Add SymbolTable to signature.
	* generator/IGeneratable : Add QualifiedName prop and update Generate
	  signature.
	* generator/Parser.cs : Switch from plain Hashtable to SymbolTable.
	(Parse): Replaces the Types property and returns a SymbolTable.
	* generator/StructBase.cs : New base class to derive struct and object
	  types. Initial implementation of protected GenField method and ctor.
	* generator/StructGen.cs : New non-object struct type generatable.
	* generator/SymbolTable.cs : New. Manages complex types hash and a
	  simple types hash.  Will provide generic lookup interface.
