Some improvements on robbyrussel theme

[bobthefish] allow git untracked files override

Showing untracked files can be (very) slow on large NFS mounts. Allow the user to disable the '...' output when there are untracked files, either globally via fish config:

    set -g theme_display_git_untracked no

 or locally via git repo config:

    git config bash.showUntrackedFiles false

Fixes #434

Fix extraneous output from `type` on some fishes.
