[aur-general] delete/merge request

[Rob Til Freedmen]

Please delete orphaned package
https://aur.archlinux.org/packages/vlc-spros-plugin/

It is a duplicate of
https://aur.archlinux.org/packages/vlc-rpos-plugin/
and
https://aur.archlinux.org/packages/vlc-srpos-plugin/
which should be merged to vlc-srpos-plugin/
- the name of the code project

I think this one can also be deleted - it is unmaintained,
outdated and skins2 is now included in extra/vlc
https://aur.archlinux.org/packages/vlc-skins2/
