* generator/CallbackGen.cs : use non-static symtab, kill doc comments * generator/ClassBase.cs : use non-static symtab * generator/CodeGenerator.cs : use non-static symtab * generator/EnumGen.cs : kill doc comments, don't gen using System here * generator/GenBase.cs : gen using System here for all types * generator/InterfaceGen.cs : don't gen using System here. * generator/Method.cs : use non-static symtab * generator/ObjectGen.cs : kill doc comments, use non-static symtab * generator/OpaqueGen.cs : don't gen using System here. * generator/Parameters.cs : use non static symtab. * generator/Parser.cs : use non static symtab. add SimpleGen's and ManualGen's * generator/Property.cs : use non static symtab * generator/SignalHandler.cs : use non static symtab * generator/StructBase.cs : use non static symtab * generator/SymbolTable.cs : major refactoring. now uses SimpleGen and ManualGen IGeneratables to simplify the method and prop code. Is now instance based with a static prop to get the singleton instance, so that a this indexer can be provided to access the IGeneratables nicely. Gearing up to remove even more code from here by accessing IGeneratables directly. svn path=/trunk/gtk-sharp/; revision=14687
