Refactor make linting more strict

[Sqrcz]

OK, here is the rest of the library refactored in the same way as in the first part (last merge)

[Sqrcz]

apart from conflicts ;)

the only two things left are warnings (not errors) related to styles being not scoped... which we need few times.

so we went from this:

3570 problems (1490 errors, 2080 warnings)
1452 errors and 1425 warnings potentially fixable with the `--fix` option.

to this:

2 problems (0 errors, 2 warnings)

:)
