Revert "Enclose author & email in quotes"

Turns out:

• The METADATA file found in the wheel's dist-info should be of the same format as PKG-INFO in sdists (PEP427)
• The Author-email field in PKG-INFO should conform to the RFC822 standard (PEP314)
• RFC822 doesn't specify anything regarding ' (RFC822)

So actually, the use of ' in package metadata is left undefined Similarly, .cfg parsers may optionally support escaping of ' with \', but this is not mandated

configparser.ConfigParser doesn't support escaping or quoting, so the workaround is:

author = First O'Last
author_email = first.o'last@example.com
license = Apache License 2.0

This breaks syntax highlighters (as you can see above), but works on pypi.org which is the only consumer of this
