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

On some browsers Batchactions block looked OK, but on others (e.t. Opera on Linux) every element in Batchactions block had different height.
The height of these elements was related to font size which is a little bit different on every OS'es and browsers.

Moved "edit tree" button into same DOM structure so
we can layout them more easily through inline-block.

Partially reverts "fixes" from 411673ed. This re-introduces the arrow on the main tree node in the CMS ("Your site name"), but that's less important than being able to navigate tree hierarchies in the first place in TreeDropdownField.
Specifically, the change removed the "add page" panel padding,
because it moved padding from .cms-panel-padded into
commonly contained elements, like .ui-tabs-panel.
Apart from breaking layouts, it makes the class meaningless,
since its only padded depending on which elements it contains.
In order to rectify some introduced inconsistencies,
much too complex were required, e.g.
.ui-tabs .cms-edit-form, .ui-tabs .cms-content-fields {...}.
Was originally added for CMS grouped actions,
but can't see any effect. Probably related to the unreleased
changes around the new "batch actions" and "add page" panel styling.
It breaks button height in the top toolbar, by shifting from jQuery
UI's (well tested) mode of applying padding to the container,
to applying padding to the contained text instead. This
conflicts with the line-height set on many buttons.
