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.
