Add more tags to the list of things the decompiler can handle. This
required some changes to track the containing object class in the
DecompileCtx, since some objects use the same tag names.
The improved support means we can test the decompiler on most of the
test suite. Any new test samples will by default be tested to ensure the
decompiler produces the original blueprint file.
Also, updated the decompiler to always use double quotes.
Use a '$' instead of a '.' to indicate a type provided in application
code.
The reason for the change is to have a consistent "extern" symbol that
isn't widely used elsewhere and isn't ambiguous in expressions.
- Add support for type checking boxed types
- Remove support for converting string and number literals
- Add the `typeof()` operator for GType literals
