$SAFE setting incompatable with Ruby 2.3.0

https://github.com/technicalpickles/jeweler/blob/master/lib/jeweler/gemspec_helper.rb#L51

$SAFE values 2 thru 4 are now obsolete with Ruby 2.3.0. As a result I get this when I attempt to do "rake gemspec --trace":

$ rake gemspec --trace
** Invoke gemspec (first_time)
** Invoke gemspec:generate (first_time)
** Invoke version_required (first_time)
** Execute version_required
** Execute gemspec:generate 
Generated: rubyneat.gemspec
** Invoke gemspec:validate (first_time)
** Invoke gemspec_required (first_time)
** Execute gemspec_required
** Execute gemspec:validate
rubyneat.gemspec is invalid. See the backtrace for more details.
rake aborted!
ArgumentError: $SAFE=2 to 4 are obsolete

Can you please merge this and release the new version of the gem? You are blocking our releases...

I apologize for not being a more active maintainer. I need help, and have filed https://github.com/technicalpickles/jeweler/issues/283 to figure out the future of jeweler.

In the short term, people could consider either using @steakknife's fork in https://github.com/technicalpickles/jeweler/pull/281, or https://github.com/flajann2/juwelier

another option: use jruby which ignores SAFE directives (FWIW :)

This problem was fixed long ago. Thanks.
