DataLad extension for functionality that was phased out of the core package

Commands provided by this extension

• annotate-paths -- analyze and act upon input paths
• diff -- old'ish implementation for differences between two states
• ls -- list summary information about URLs and datasets of a dataset (hierarchy)
• publish -- original implementation, replaced by push in core
• metadata commands search, metadata, extract-metadata and aggregate-metadata; moved out of core in favor of the datalad-metalad extension

Procedures provided by this extension

• cfg_metadatatypes

In addition, this extension provides the AutomagicIO feature that patches Python's open() function to automatically obtain file content, if needed.

It also provides the web user interface that is used at http://datasets.datalad.org (yet to be migrated to https://github.com/datalad/datalad-webui fully).
