win32metadata should have sensible defaults

• I have searched the issue tracker for an issue that matches the one I want to file, without success.

win32metada should have reasonable defaults so that Squirrel shortcut creation works out of the box as expected.

Currently, https://github.com/electron-userland/electron-packager/blob/master/docs/api.md#win32metadata defaults to an empty object AFAIK and therefore the default metadata from Electron is left intact.

This results in lots of questions like "Why is my Squirrel shortcut called 'Electron'?". This can be solved by simply providing logical defaults for the win32metadata option as follows below. Where "p" === "package.json"

Key	Mapped Value
ProductName	config.name or p.productName or p.name
InternalName	config.name or p.productName or p.name
OriginalFilename	config.name or p.productName or p.name
FileDescription	p.description
CompanyName	p.author

This is just a proposal, feedback on this welcome 👍

I like this, I've been waiting for someone who has a Windows machine to write something that I can understand for sensible defaults for the metadata fields 😅

About CompanyName: per electron/forge#160 we should probably be more specific about this, since it can be an Object.

I have Windows instances available so let me know if I can be any help.

@jacobq I think this one doesn't absolutely require Windows instances, but if you're volunteering them, a) seeing if you can reproduce #590 and/or #597 and b) figuring out what's going on in either would be greatly appreciated 😅

The person who implements this should use the parse-author module like in electron/forge#161.
