Previously, `object` and `none` were both top-level types. This made decompilation rather messy as they have no LCA and resulted in a lot of variables coming out as type `none` which is very very wrong and additionally there were plenty of casts to `object`. This changes it so `none` becomes a child of `object` (it is still represented by `NullType` which remains unusable in compilation). This change makes `object` the sole top-level type, and the type that can represent *any* GOAL object. I believe this matches the original GOAL built-in type structure. A function that has a return type of `object` can now return an integer or a `none` at the same time. However, keep in mind that the return value of `(none)` is still undefined, just as before. This also makes a cast to `object` meaningless in 90% of the situations it showed up in (as every single thing is already an `object`) and the decompiler will no longer emit them. Casts to `none` are also reduced. Yay! Additionally, state handlers also don't get the final `(none)` printed out anymore. The return type of a state handler is completely meaningless outside the event handler (which is return type `object` anyway) so there are no limitations on what the last form needs to be. I did this instead of making them return `object` to trick the decompiler into not trying to output a variable to be used as a return value (internally, in the decompiler they still have return type `none`, but they have `object` elsewhere).
