Add Mountain Lion-notifications-compatible growlnotify script.

This accepts the same args as Growl's growlnotify
script, but displays notifications in Mountain Lion's
Notification Center, instead of in growl.

Before using this script, install the `terminal-notifier`
gem in your default ruby:

  [sudo] gem install terminal-notifier

bin/growlnotify

+#!/usr/bin/env ruby
+# encoding: utf-8
+# == Synopsis
+#   Requires the terminal-notifier gem ([sudo] gem install terminal-notifier)
+
+#   growlnotify wrapper to turn Growl alerts into Mountain Lion notifications
+# Uses growlnotify option syntax to keep your old scripts working with the new shiny.
+#
+#   If you use Growl via growlnotify in your shell scripting, this script
+# will replace Growl's alerts with Mountain Lion notifications.
+# Name this script `growlnotify`, make it executable and replace
+# `/usr/local/bin/growlnotify` (your location may vary) with it
+# Now you shouldn't have to update any of your existing tools.
+#
+# == Examples
+#   Send a Mountain Lion notification with title and message
+#     growlnotify -m "message" -t "title"
+#
+# == Usage
+#   growlnotify -m "search string" [-[tn] "title"]
+#
+#   For help use: growlnotify -h
+#
+# == Options
+#     -m, --message MESSAGE            Copy just the url, defaults to full HTML tag
+#     -t, --title TITLE                Title
+#     -h, --help                       Display this screen
+#     -v, --version                    Display version info
