git-jump: pick a mode automatically when invoked without arguments

When `git jump` is invoked with no positional arguments (and no arguments after `--stdout`) it currently prints usage and exits with status 1. But there are two situations where we can usefully infer the most valuable and likely mode that a user would want to use, and select it automatically: 1. When there are unmerged paths in the index, the user likely wants `git jump merge`. 2. When the working tree has unstaged changes, the user likely wants `git jump diff`. In this commit we teach `git jump` a new "auto" mode which detects these cases and dispatches to the corresponding mode automatically. The user can either explicitly spell out `git jump auto`, or just leave it at `git jump` (because "auto" is the default). If none of the interesting cases listed above applies, then auto mode falls back to the existing usage-and-exit behavior.
