[aur-general] Delete vim-notmuch

[Felipe Contreras]

Hi,

I packaged this plug-in as a standalon vim plug-in, however, nowadays
it's bundled with the official 'notmuch-vim' package already.

In theory I could update the package for the people that want to have
the latest and greatest version without having to wait for a notmuch
release. However, those people are better served by using a plug-in
manager like pathogen and use the Git repository.

Cheers.
