[PATCH 1/1] css: use less blurry icon for external link

[Christian Hesse]

From: Christian Hesse <mail at eworm.de>

Your mileage may vary, but for me the old icon looks blurry. The new
one is character 0xf08e from OTF font awsome in size 10.
The icon color is black, gray level is adjusted via opacity.
