Timo Tijhof 481c90798e Make extra <span> in Vector tabs optional
Applying calculation measurments to have full pixel equivalent to
`em` based properties that are necessary for user font scaling
preference ability.

Also:
* Changing watchlist icon to `em` based sizing and remodulate positioning
  by putting it on `:before` elements.
* Changing calculation of `.vectorMenu h3` to acommodate down arrow indicator.

TODO:
* Remove the extra <span> (in separate commit, to make it easier
  to rest cache compat during code review).
