base javascript: Tweak variable highlighting

This commit avoids false positives when highlighting literals such as
`$window`, which is a regular variable but still highlighted as a
special value.

Special highlighting of variables that start with a dollar sign `$`
was also removed, as not all variables start with a dollar sign,
and we don't have a reliable way yet to detect variables.
