A lookup tag with no type attribute would crash the decompiler, even if
that was valid. This wasn't caught by the tests since blueprint never
generates such XML.
Also fixed a bug in the tests that caused decompiler-only tests not to
run.
- Added tests for more error messages
- Test the "go to reference" feature at every character index of every
test case
- Delete unused code and imports
- Fix some bugs I found along the way
Libraries can add new deprecations, or the environment you're running
the tests in might have old libraries where the things we test aren't
deprecated yet. Move the deprecations test into its own module with its
own code, so it can check library versions and skip the test if it won't
work.
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.
