from 2-dev

Similar to writeas/writeas-cli#22, this change runs goimports on all
files and changes the recommendation in the Contributing section to do
the same.

This adds a new constructor to build Clients which operates on a Config
struct rather than positional parameters. This will enable adding new
parameters in the future without breaking the API.

To begin with, this introduces a new URL parameter that wasn't
previously available. An example of another parameter that could be
added in the future is the timeout (to override the default timeout).

Existing constructors have been transitioned to the new one because it
implements a superset of their functionality.

Minor note: The Tor constructor wasn't respecting the default timeout
but with this version, it does.

Resolves #8

This uses a local proxy to communicate over Tor. Code is from the
writeas-cli.

Plus break up internal request building so we can optionally send query
parameters with some requests (like DELETEs!)

Plus fix Client post func and rename SubmittedPost to PostParams.

Includes ability to make authenticated requests and get posts.

Backend now uses a cipher suite that Go supports.
