Update coding style after pycodestyle 2.1.0
In pycodestyle 2.1.0, E305 was introduced, which requires two blank
lines after top level declarations, too.

See https://github.com/PyCQA/pycodestyle/issues/400

Philipp Hagemeister 3eff81fbf7 [jsinterp] Disable comment support
We need a proper lexer to be able to understand YouTube's code, which contains /* inside of strings.
For now it's sufficient to just disable comment support altogether.

Fixes #4976, fixes #4979, fixes #4980, fixes #4981, fixes #4982.
Closes #4977.
