Script Code and Template Text editors; "Compare" button now displays differences in a non-modal window

Script Code and Template Text editors which are available on various forms have a "Show/ hide compare panel" button.

When the right-hand "compare" panel is displayed, a "Compare" button below it allows the content of both panels to be compared.

Previously, the Compare window was displayed modally. This is now non-modal making it easier to copy code to other windows.
