Revert "Adding license annotation to js files."

This reverts commit 8cb24652cb, due to
the fact that the new annotations caused our binary size to jump
by 52%.

The compiler preserves all 'unique' licenses, which causes trouble
since the comment blocks with the license annotations are not unique
and contain file overview comments as well.

We can re-examine this once we have restructured the license headers.
