writeas v2.0 / wf v1.0

This version supports all the Write.as API v2 functionality: 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
• Publish to your blog with writeas -b <blog-alias>
• 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 all anonymous posts, including ones on your account when authenticated
• writeas-cli is now licensed under the GPL, instead of MIT

Fixes:

• Fix writeas delete errors not displaying
