This has been discussed, but we'll finally be doing it for the next
major version so that we can introduce a few features that depend on
gems that don't support 1.9.
Colocates the helper methods for looking up a uname by renaming them to
have the same prefix as the base method (i.e. `get_uname`).
Also adds an additional rescue in case we try to run an executable on a
system but it wasn't founded (this should never happen).
Also adds some tests to make sure that each method gets at least a very
basic amount of exercise in the test suite.
This moves away from rest-client's convention of using symbols as header
names so as to present less obfuscation as to how these are actually
named when they go over the wire.
Because headers can be injected via the bindings' API I was initially
worried that this change might break something, but upon inspection of
rest-client source, I can see now that headers take precedence as
assigned by their insertion order into the header hash, and are
"stringified" in that same loop [1]. This means that even if a user
injects a symbolized header name (`:idempotency_key`), it will still
correctly overwrite the one generated by stripe-ruby despite that using
the string format (`"Idempotency-Key"`).

- When performing requests on the behalf of a managed account, `stripe_account` option must be passed everytime, this can become redundant
- Allowing to set the `stripe_account` globally makes thing easier for wrapping every request in a single method, the same way as it is for defining the `api_key` globally
As requested in #370, this will allow advanced users to configure a
certificate bundle that is expected to be more up-to-date than what
we've managed to include with the gem.
