v1.6.0

• New command: git-wip. This will create quick save point
  commits for Work In Progress (WIP). This creates quick commits
  without writing a commit message.

• git-initial-commit will now report the more user-friendly error "No commits
  yet" for an empty repo (#46, thanks @Shea690901 and @ernstki!)

• git active-branches now supports a -s <date> option (for --since),
  where you can specify the threshold for what is considered "active" (#36,
  thanks @ernstki!)
