Ruby 2.1.2 fixes

[monban]

Cleanup for Ruby 2.1.2. Everything seems to be working without errors or warnings EXCEPT #34, which is sporadic.

Thanks for pointing out my over-complication of things. I went ahead and tested the pure OpenSSL::Digest.new("sha512") on Ruby 1.9.3 (as I should have in the first place...) and as you said, it works fine.

I would still like to avoid "pessemistic dependency" warnings when building the gem. As long as only the minor version changes there shouldn't be any breakage, in theory, only bugfixes right?

I haven't been developing under major external dependencies long enough to know how true or not that might be. I will just leave that one to your discretion, thanks.

If only ruby gems actually worked that way! I see what you mean now about the warnings:

I'll take a look at using newer versions of them, particularly nokogiri, which broke in the initial 1.6.0 release. It's probably better now.
