this changes all api calls to respect the flags for tor and tor-port

- config now has TorPort method to return flag value if set, or default
- api now only has newClient, this creates a tor client when flag is
present. does not need to be exported anymore
- no methods take a tor argument as no longer needed
- all commands now share the same behaviour logging tor messages
- api.torClient was removed as not used anywhere
- all calls to api.newClient now check for and return the error
- api.HandlePost was removed as redundant of api.DoPost

this changes imports to use the github import path
github.com/writeas/go-writeas/v2

this adds the ability to claim local posts under an authenticated
account.

removePost is now exported for use the claim command

fix tabwriter padding

adds subcommand colls
lists collections for authenticated user
supports -url flag for listing collection URLs

changes command for delete to return errors to the user

also updates comment for DoDelete

This changes the 'posts' subcommand, previously 'list', to also list any
remote posts for the user if currently authenticated.

- adds DoFetchPosts to the api pkg which returns all the logged in users
posts.
- adds a RemotePost type to the api pkg which stores some of the return
information from DoFetchPosts for use in printing to stdout
- adds GetUserPosts to the api pkg which converts the incoming
writeas.Posts into the smaller RemotePost type
- adds getExcerpt which takes the incoming writeas.Post.Content and
returns a trimmed down excerpt of the content. Max 2 lines of 80 chars
and delimited by '...'
- changes CmdList from pkg commands to CmdListPosts which now writes out
any local and remote posts in simple formatted tables

this adds a configurable directory, currently within the users path for
the configuration, user and post data to be saved.

it is accessible down the stack of the application via the cli.Context,
specificaly c.App.ExtraData which is a function that returns a map of
[string]string under the key 'configDir".

this splits everything out into shared packages

- user config and application config share a package for now
- sync is part of the api package which includes the client, posts and
tor logic
- logging is it's own package
- commands are in their own package

first moving everything out into the base package
should be followed by some refactoring and reorganizing before creating
two different binaries for write.as and writefreely

As discussed in #20, this runs `goimports` on all Go files separating
imports into two groups: standard library and everything else.

This returns URLs with Markdown enabled. Part of #14

Leave out -u option in writeas auth command

Only with `writeas publish` right now, and only if posts directory has
already been set up.

This adds a new parameter that determines whether or not authentication
is required, and also returns an error now.

Closes #16

If you're logged in, now requests will be made with the saved token

Instead of using an INI file for the access token, this stores it and
other user information in a single JSON file.

Adds new `writeas auth` command and saves user's access token to a new
local configuration file.

This closes #10 / T191

This closes #9
