[aur-general] Delete request: irssi-mouse

Hello, The package irssi-mouse [1] can be safely removed since the patches are outdated and in the meanwhile also offline. In addition there is a new package irssi-script-mouse which brings the same functionality to the current version of irssi as a plugin. Thank you, Moritz [1] https://aur.archlinux.org/packages/irssi-mouse/
