testing/cgit-pink: new aport

https://git.causal.agency/cgit-pink/ web frontend for git

cgit-pink is a fork of cgit. Upstream cgit has long been stagnant, with the vast majority of patches sent to the mailing list going silently ignored, despite their obvious merit in many cases. This fork aims to incorporate a number of existing patches as well as to provide a friendlier place to send new patches. They will, at the very least, get a reply. This fork also aims to make new releases which can hopefully be picked up by package repositories, making it easier for users to run an improved cgit.
