This edge case can occur when a large tree is cached in HTML already,
without any nodes expanded via ajax. If a new node is added with
a parent that's not existant, it was simply placed on the root node.
This is a display bug, a full CMS refresh fixes it.
Fixes a related bug where tree causes (view) duplicates,
where the same node is rendered twice. This was due to the whole
subtree being refreshed (including the new node) through jstree's
built-in "open"/"select" events, while at the same time
creating a new node through updateNodesFromServer() callbacks.
Also added a global tree loading indication to make it clear
that the tree is still processing.

DO NOT MERGE: to be reviewed.
This feature request was born out of wanting the ability to disable (for example) a top level page from being selected, while still being able to select a child page. Using setFilterFunction() simply removes the node and its children.
Extra styling for disabled nodes
Disable ability to select a disabled node for TreeDropdownField
Disable hover CSS changes
Fixing merge conflict during rebase
Return a boolean for nodeIsDisabled()
Removed trigger background. Incidentally this also makes it less
obvious that the trigger has too much padding on the right
(which I can't figure out ...)
450px width are often not available to the dialog (with all margins/paddings subtracted from the window).
Ensure the URL doesn't cause an unnecessary wrap. Ideally we can size this to the dialog width
automatically of course.
Rendering potentially 1000s of nodes can exceed the CPU and memory constraints
of a normal PHP process, as well as the rendering capabilities of browsers.
Set a hard maximum for the renderable nodes, deferring to a "show as list" action
in the main CMS tree. For TreeDropdownField, we don't have the list fallback option,
so ask the user to search for the node title instead.
Also makes both the "node_threshold_total" and "node_threshold_leaf" values configurable
Fixed what I believe to be a few very minor CSS regressions, that appeared after the CSS restructure for the side-by-side preview.
- Reverted background of the right panel (and tab active state) to the slightly darker shade (as per 3.0) to keep each of the 3 panels visually separate.
- Slightly increased padding on ui-tabs-panel as felt a but too close for comfort. Had decreased since 3.0.
- Decreased padding for logged in user name in menu, felt too excessive. (3.0 was neater)
- Evened out padding above buttons in site tree sidebar
