Initial check-in of plugin
Now always saves the image of the diagram when the user returns from the Gliffy editor, we assume the user has updated the image.
The image is saved using the diagram ID so the wiki page will always reference the most up to date diagram.
Now just gets the image instead of first getting the URL to get the image, and then getting the actual image
Now in a working state, opens the gliffyWrapper in a new tab, then updates the page when back to wiki button pressed.
Now stores the Gliffy object in the session so when updateToken is called it doesn't actually have to update the token everytime.
Also now retries up to 5 times when downloading the image.
Added ability to update the diagram image in case the diagram has been modified outside of the wiki.
Changed the plugin to only require a one line "diag" tag instead of an opening and closing "glif" tag.
