Started work on the anonymize endpoints.
Create anonymous user on startup, fixed sharing endpoint.

Donkey will now create the anonymous user on start up if it doesn't
already exist. The /secured/filesystem/share endpoint was fixed to use
the new permissions format.
Removed the anonymize endpoint, it isn't needed.
Added the LICENSE file.
Initial commit of common-cli.
Fixed the tools.cli dependency.
Fixed some usability issues in common-cli.
Added more docs to common-cli.
Fixed a spacing issue in the (usage) function of common-cli.
Merge branch '1.8.7' into rewrite
