Since ActiveSupport is modular just include the #blank? inflection extension rather than including all of the core extensions and active_support itself.
It seems heavy-handed to require all of ActiveSupport's core extensions as a side effect of including an exception reporting API. According to 2ba25e8 this include was required for #blank? and #to_xml. I found references to the former but didn't find any to the latter. This pull does two things:
My motivation for this change is a problem I'm having with using Airbrake in a jruby application that makes use of threads. Due to the way autoload works, I'm seeing threads blocking each other when dealing with JSON coercion with active_support required.
Cherry-pick Object#blank? extension

Makes a lot of sense. Yeah, I've checked and we're not using #to_xml from ActiveSupport, we're defining our own.
Since we're really including ActiveSupport only to use #blank?, a better solution would be to get rid of that dependency.
