[treeview] async support for complete refresh

[joern]

From the mailing list:

We're still having problems implementing a 'refresh' button for a treeview tree. We need to be able to re-initialize the tree, clearing out the current version completely, and reloading with data fresh from the server.

we're clearing out the current tree with: $('#openExistingTree').empty();

and then re-initializing with $('#openExistingTree').treeview({ url: "CalcBldrOpenExisting.ashx" });

Each time we hit 'refresh', we're getting a duplicate set of 'hitarea' divs

The initial json returned is:

"[{'text': 'Private Drafts','id': 3, 'hasChildren': true},{'text':
'Shared Drafts','id': 4, 'hasChildren': true},{'text': 'Published
Calculations','id': 5, 'hasChildren': true}]"

"clear everything and recreate the root element"
