Owlkettle 2.0.0 is a declarative GUI framwork for GTK 4

[planetis]

Just wanted to say that I've being toying with owlkettle and it looks amazing! 
It's the first time I had the patience to start learning about GUIs. I like the 
fact it builds upon an existing framework which has it's own examples and 
documentation. As for the DSL I like that you can write attributes as a list 
and as separate statements, when the vertical space runs out. I think it's fine 
as it is. Again amazing library!
