Version 0.17

This release adds dependency resolution for the down command
and fixes a bug that occurs when trying to update a repository that
has more than 250 packages.

• New: down command learned -r and -o flags that resolve dependencies
  and write a recommended order of compilation for any downloaded packages.
• Bugfix: issue #28, in which AUR queries for a local database with more
  than 250 packages failed.
• Update: better error messages when pre/post command actions fail.
• Update: somewhat improved zsh completion (contributed by KoHcoJlb).
• New: generated bash completion via the cobra library.
