multiple directories in watch

[dakom]

now that it's possible to add a path to watch (#350 ) - I'm not sure how to add multiple paths.

The syntax for cargo watch itself is to have multiple -w args

I think on the toml side it'd feel natural to have an optional list of paths. e.g.:

watch = { watch = ["./crate1/src", "./crate2/src"] }

no problem.
