Rework multiline comments

[FPtje]

I was working on #163, and found myself in a bit of a rabbit hole: I tried to implement the following suggestion:

I guess what may be surprising here, is that returns and statements are counted differently. You can have a simple return, but not a simple statement instead of a return. Language wise a return is different from a statement, because it must be the last thing in a block. Conceptually though, it lives on the same level.

Maybe I can change the logic to one simple statement or a simple return

I found glualint to go in an infinite loop. The reason was because of how comment rendering logic depended on whether something is rendered multiline. But then the decision on whether to render something multiline depended on whether there were comments.

The solution is to remove the dependency "Comment rendering -> Multiline", and to only have it the other way around. This has quite some drastic consequences. Some attributes can be removed, others have to be reworked.

This PR keeps track of progress and TODOs.

TODO

• Tables like {"a", "b", --[[comment]], "c"} are printed as multiline until the comment. After that it is printed single line
  • Personal note on how to solve this: inh field list forceMultiline, set to @hd.multiline or not null $ comments
• Implement rendering comments after function arguments: foo(a, b --[[comment]], c)
• Add some more tests regarding tables, function arguments.

I'm really happy with this change. The comments used to all be collected and printed at the end. Now they're printed along with the argument. Besides that, having comments in function calls causes the function to be considered multiline.
