Add JavaScript to force EntryDetail box to scroll down with page

[bobharner]

On the Home page, when there is a long list of entries, scrolling down and clicking on an item lower down on the list has no apparent effect -- you have to scroll back up to see the entry detail.

What would be cool is to wrap a component around the entry detail div that uses JavaScript to keep the entry detail in view at all times. Something like http://www.vanvanvans.com/designer (but it would be best if it could be done using Prototype/Scriptaculous so we don't have to add JQuery to the stack).

This could maybe be implemented as a "KeepInView" mixin that could be attached to any component.

http://jqueryfordesigners.com/fixed-floating-elements/ provides more technical details, although it uses JQuery.

We've switched to jQuery, so this should be a bit easier now, following the jqueryfordesigners.com example cited above.
