accept alternative maintainer email for build_win

[maxheld83]

I'm guessing this is a common scenario:

1. I'm working on a fork of some maintainer's R project
2. I'm ready to open a PR and want to make sure that it passes R CMD Check on all platforms ...
3. ... so I use the great build_win
4. ... and realize a couple of seconds too late that the resulting email will be sent to the maintainer of the project.

Would be nice to specify an alternative email address to build_win as an argument.

Win-builder simply uses the maintainer's email address, so this would require modification to the DESCRIPTION file before uploading.

I do agree that in general that something like this would be useful - perhaps a confirmation prompt that says "message will be sent to person@foo.com", before uploading the package?

We could use as.person(eval(parse(text=getOption("devtools.desc.author"))))$email as e-mail address, and perhaps a prompt (in interactive mode) or an argument that allows overriding the maintainer's mail address (for scripting). Not sure if this will make everybody happy, though.

I think it would be fine as an argument to build_win(). But modifying the DESCRIPTION file is a pain.

I'd be happy to accept a PR that implemented this.
