Enable \citeauthor to be used for citations

[TimvdLippe]

Per https://tex.stackexchange.com/a/69381/155506 using plainnat of the natbib package makes \citeauthor{citation} work. By specifying [numbers] on the package statement, there is no visual difference in the actual bibliography and we remain using numbered citations.

CC @Keraito You probably want this as well

Why do you prefer to use \citeauthor over \cite?

[TimvdLippe]

It is not a substitution, but an addition. With this change you can use BOTH \cite and \citeauthor. For example I use it in:

The implementation in WatchDog Eclipse is inspired by the $O(ND)$ algorithm introduced by \citeauthor{myers1986ano} \cite{myers1986ano}.

Yeah, that's clear. \citeauthor does "the right thing when citing a paper via their authors" (in terms of et al., and, etc.), so I see the point now.
