setopt lines break when not run through bash

[tsangal]

gibo/gibo

Lines 6 to 9 in bd5710b

	set -o errexit
	set -o noclobber
	set -o nounset
	set -o pipefail

On my system (Linux Mint) /bin/sh is symlinked to dash. Thus, executing the gibo script directly from the command-line no longer works due the the "set -o" lines at the top of the script.

$ ./gibo update
./gibo: 9: set: Illegal option -o pipefail

I have to run it through bash explicitly (e.g. bash gibo update).

Oops, my bad. Thanks for reporting! Reverted in 090c376.
