Remove httparty dependency & monkey patches? #23
Description
I'm trying to reduce the dependencies of my projects, and googl has a dependency on httparty, but uses almost no functionality of it. I replaced it with net/http in 65 LOC, and all tests remain green.
Also, I removed the monkey patches (to_openstruct and underscore) and replaced them with methods in the Googl::Utils-module.
If you are interested, I can put together PR with these changes.
