Right now, and unless the stringsAsFactors option has been modified globally, ggnetwork automatically converts strings to factors when importing vertex and edge attributes:
> data(emon, package = "network")
> str(ggnetwork(emon[[1]]))

Let's keep that default behaviour, but allow the user to change it if need be.
The problem above is shown with fortify.network. It also affects fortify.igraph, which suffers from another issue on top of that one: see #54.
