Make it easy to add cordova plugins to meteor just from knowing the github url.

meteor_add_cordova.sh

#!/bin/bash

# Given a github url for a corvoda plugin, such as 
#
# https://api.github.com/repos/cordova-sms/cordova-sms-plugin/
#
# this node.js script will generate the appropriate format for "meteor
# add" using the last commit for the tarball and pass it to meteor add.
# For instance, for the above:
#
# cordova:com.cordova.plugins.sms@https://github.com/cordova-sms/cordova-sms-plugin/tarball/17c4da078f6c0d9f762ac10f5015440ee1c81d07
#
# You can now do (in your meteor project directory):
# 
# meteor_add_cordova.sh https://github.com/cordova-sms/cordova-sms-plugin
#
# Requirements: 
#    npm install -g request xmljson
#
