Replaced my private email with github email

[Nashenas88]

The current email is my work email, and I've seen spam coming in through this. I'm switching it to my github private email

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @nikomatsakis (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. The way Github handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see CONTRIBUTING.md for more information.

Sorry about the spam problems, hope it helps.

No worries. I just had a couple of really strange emails in Russian and Chinese. Once I saw the email address on the blog post it hit me. I caught it before it got bad ;)
