[aur-general] Merge request: pipe and pipe2

Hi, I just updated the pipe [1] PKGBUILD. There is also pipe2 [2], which is the same program, but outdated (last updated in 2012). The best thing here would be to merge them into 'pipe2'. [1]: https://aur.archlinux.org/packages/pipe/ [2]: https://aur.archlinux.org/packages/pipe2/
