An alternate LESS compiler library that I am evaluating
(https://github.com/oyejorge/less.php) barfs on the '!ie' syntax, but tolerates
the underscore hack.

Based on the discussion on T56307, this change is controversial
and not necessarily wanted. In summary:
* Green star looks out of place with blue Vector (Edokter, Esanders, Trevor)
* Clashes with WikiLove heart icon (Edokter)
* Flat design doesn't fit with Vector's gradient style (Rillke)
* Green means constructive in MediaWiki UI, however clicking the
green star removes a page from your watchlist (Krinkle)
This reverts commit 56825d209e.
