feat/Move the category field to Element (#3056)

It's pretty basic change, just literally moved the category field to
Element class. Can't think of other changes that are needed here,
because I think pretty much everything expected the category to be
directly in elements list.

For local testing, IDE's and linters should see difference in that
`category` is now in Element.
