[PATCH 2/3] about: send images plain

[Christian Hesse]

From: Christian Hesse <mail at eworm.de>

The about page used to display just fine, but images were broken: The
binary image data was embedded in html code.
Use cgit_print_plain() to send images in plain mode and make them
available on about page.
