[arch] new vi, vim, gvim in testing

[Tobias Kieslich]

Ola;

After some time we used post_install magic to make the vim binary more
capable and some people complaining about vim not having x features
while gvim is not installed I decided to separate all packages. This
means we have a new layout of the packages:


 * vi - serves vi binary only, ex, vidiff and the whole runtime. No
   X-server capabilities, and it listens /etc/virc and ~/.virc only!
   This is the only package that comes with base. vim moves to editors

 * vim - X capabilities(can drag splits in xterms, runs as server
   etc), Ruby,python and Perl-support. listens to
   /etc/vimrc ~/.vimrc

 * gvim - like vim but with gtk2 interface and listens to
   /etc/gvimrc and ~/.gvimrc

The reason is that people complaint about missing X support in vim
sessions, and for some people the symlinks screwed
up.
