Remove dependence on bash in install.sh

Browse Source 
Replace bashisms with syntax supported by all posix-compliant shells.
The echo command does not support -e in many simplified shells
(including dash) so printf is favored.  The [[ ... ]] notation is also
not accepted by all posix shells so [ ... ] notation is used instead.
