LDEV-4017: Making add lesson and course grouping dialogs size based on screen size rather than a fixed minimum size. Changed Notifications for org to be based on the parameter orgID rather than dialog's orgID as the dialog isn't fully set up at this point, causing a javascript error.
LDEV-4014: Remove help button from tab as it only points to one help page, whereas the help buttons in the main part of the monitoring page point to a different tab for each page.
