[arch-dev-public] cleaning up [testing]

So, let's sue the short period while testing is low on packages to clean up some orphans: * xulrunner: no need for this to be in testing. The additional ld.conf file should not hurt * courier-imap: why is this in testing for so long anyway? * proftpd: dito * wpa_actiond: new package; no need to be in testing -- Pierre Schmitz, https://users.archlinux.de/~pierre
