paket update for fake runner FSharp.Core 4.7

[drssoccer55]

Response to error message saying FAKE runner uses FSharp.Core 4.6 instead of latest FSharp.Core. I've worked around it locally but think the runner should be updated.

Following instructions from issue 2001

Forked, cloned, paket update, and submitted PR.

Whoops forgot this update broke me too. Will have to update FAKE to get rid of the namespace.

Travis CI build failed. Looks like an issue for generate docs where it is trying to execute a command with a list of dlls and failing because it is an empty list. Unclear to me at the moment why paket update broke this.

Thanks for looking into this! Sometimes it's really frustrating to get things working again after paket update ...

One problem might be that FSharp.Core no longer supports netstandard1.6 and we still build some stuff for netstandard1.6. I'll take a look
