Shrinkage

• The fetch/push-anywhere functionality (XDLRA git-annex backend and datalad-annex:: Git remote helper) has been remove. It has been reworked and improved, and is now released as part of https://github.com/datalad/datalad-next (version 0.2.0)
• The export-to-webdav has been discontinued, and is no longer shipped with this extension. A superior and more standard approach is available from https://github.com/datalad/datalad-next (version 0.2.0), which provides a create-sibling-webdav command, and enhanced the standard push command to be able to automatically export to special remotes.
