Update for gemfile windows support

* Exclude gems that don't work on windows (kgio, dalli, gctools)
* Add new gems necessary on windows (memcache-client as dalli
replacement, tzinfo-data)
* Update gems where the old version couldn't be installed on windows but
the new version can (nokogiri, pg, bcrypt)

I don't think this should break anything on non-windows platforms since
the additions/removals only take effect on windows, and the version
updates don't appear to have changed anything huge.
