update to rails 3.0.20 to address CVE-2013-0333

refs #2097 - update test to include stderr redirect

fixed broken test on ruby 1.9

fixes #2061 - test if oVirt API has HTTPS redirect

rest_client will refuse to follow redirects on POST requests, so the URL must
be entered as HTTPS. Don't require HTTPS as dev environments may be HTTP-only.

fixes #1834 to get foreman running under ruby 1.9.3

refs #2023 - always write using_storeconfigs default as a boolean

fixes # 2056 - add bmc support to the api-proxy class

fixes #2030 - define instance variables during ERB evaluation when not using safemode

fixes #2020 - PuppetSetting is an instance, not class

fixes #1995 - enable param class ENC by default on Puppet 2.6.5+
