Write.as CLI v2.0

[thebaer]

This supports all the Write.as API v2 functionality, namely accounts and blogs.

New:

• Authenticate with writeas auth username
• Log out with writeas logout
• Sync local anonymous posts to your account with writeas claim
• Publish a file with writeas publish filename
• View a list of your blogs with writeas blogs
• Update a post's language with writeas update --lang en

Changes:

• Now you'll list your posts with writeas posts instead of writeas list -- it shows any local anonymous posts, and posts on your account when authenticated
• writeas-cli is now licensed under the GPL, instead of MIT

Fixes:

• Fix writeas delete errors not displaying

just heads up, there is currently no flag, global or otherwise for user

Ah, good catch :+1: Was copying things over from commit messages and forgot that it'd changed.

This still needs some final tweaks, but I'm going to merge now to simplify the pull request process.
