ESCLParser can now parse bitfield constants in the form (1 << n).
Added a workaround for enums named as "FooFlags - bitfield" which where converted to "FooFlagsFlags". They are now converted to "FooFlags".
Added flow attribute to function parameters. Parameter names ending with "ret" (e.g. errcode_ret) have a flow of "out". Everything else currently has a flow of "in".
Fixed conversion of "unsigned [byte|short|int|long]" parameters (they are now converted to [byte|ushort|uint|ulong] respectively).
