Script Editor; Current line is now highlighted

The current line that the insertion point is on is now highlighted in the Script Editor when it has input focus.

This helps visually locate the current line and is particularly useful when editing Portals via the IDE page when a "Find in all Files" has been performed and you double-click (or use the drilldown button) through the results grid and also when using the function list on the right of the HTML Editor to go to a JavaScript function.
