Build script doesn't work with Drush 6

[bwebster719]

Drush 6 doesn't understand the --component=root flag in the command "drush site-alias @self --component=root". Therefore, to get around this, I modified my copy of scripts/libs/luggage.sh

I replaced the line:
DRUPALROOT=$(drush site-alias $ALIAS --component=root)

With:
DRUSHVERSION=$(drush --version --pipe)

if [[ $DRUSHVERSION == "5."* ]]
then
DRUPALROOT=$(drush site-alias $ALIAS --component=root)
elif [[ $DRUSHVERSION == "6."* ]]
then
DRUPALROOT=$(drush site-alias $ALIAS --format=csv --fields=root --field-labels=0)
else
echo "Unknown version of Drush" && exit 1
fi

This should work in both Drush 5.9.x, as well as 6.x. I've ran it a few times in 6.2.0. If you have a newer version of Drush, it will exit the script gracefully

I'm playing with this on my own fork at https://github.com/jrearick/luggage/blob/issue14/scripts/libs/luggage.sh. Tested locally on Drush 5.9, but when I tried on a box I have drush 6.0 on, it fails.

drush doesn't know what --field-labels is on the line:
DRUPALROOT=$(drush site-alias $ALIAS --format=csv --fields=root --field-labels=0)

I got it to work by changing the line to:
drush site-alias @self --fields=root --format=list

Still have some further testing to do.
