add worktree.guessRemote config option

Some users might want to have the --guess-remote option introduced in
the previous commit on by default, so they don't have to type it out
every time they create a new worktree.

Add a config option worktree.guessRemote that allows users to configure
the default behaviour for themselves.

+worktree.guessRemote::
+       With `add`, if no branch argument, and neither of `-b` nor
+       `-B` nor `--detach` are given, the command defaults to
+       creating a new branch from HEAD.  If `worktree.guessRemote` is
+       set to true, `worktree add` tries to find a remote-tracking
+       branch whose name uniquely matches the new branch name.  If
+       such a branch exists, it is checked out and set as "upstream"
+       for the new branch.  If no such match can be found, it falls
+       back to creating a new branch from the current HEAD.
