Just filling in a few remaining bits and pieces from this month's work.

• Made the assistant periodically check glacier-cli for archives that are ready, and queue downloads of them.
• The box.com configurator defaults to embedding the account info, allowing one-click enabling of the repository. There's a check box to control this.
• Fix some bugs with how the standalone images run git-annex.
• Included ssh in the standalone images.
• Various other bug fies.
