Script Summary: Enable replies (of a sort) to one or more tumblr notifications; based on work by Jeremy Cutler
To use, right-click on the square icon on the right side of each notification. Shift-right-click in order to reply to multiple notifications.
0.6.1 - Tumblr updated and broke the script; refixed it.
0.7.0 - update for tumblr's new dash; changed the action to use right-click instead so it doesn't interfere with the normal left click action that lets you open the post
