Small articulation map editor tweak

[Steve Harder]

When duplicating an articulation, have the new articulation appear just below source articulation in list.

Or provide scrolling up through the list if moving a duplicated articulation from the bottom of the list, now you can just move to top of list as displayed in window.

And be able to select a group of articulations and then move them.

As an aside I LOVE that when you doubleclick an articulation name to edit it the text size and cursor position remain the same.  Unlike when in main Cakewalk and editing track name, where you have to reposition cursor because text size changes.

Thanks for all the work you have put into articulation maps!!
