Modified to enable tree view to be expanded or collapsed using tree view controls or via new buttons to fully expand and fully collapse the tree.
Tree view now is now collapsed when dialogue box in shown.

Added new CanCollapse property to TCheckedTVFrame to enable tree to be expanded and collapsed by means of buttons next to expandable items or using mouse or keyboard.
Also added ExpandTree and CollapseTree methods to allow tree to be fully expanded or collapsed.

Implemented support for allowing searches to refine previous searches instead of always working on whole database.
Modified Find Text and Find Compiler dialogue boxes to enabled scope of search to be specified.

Renamed some method parameters.
Re-arranged some methods in class declaration.

* XMLDoc commented unit.
* Lifted requirement for non-empty array passed to TCtrlArranger.RightOf method.

Added several new methods to TCtrlArranger.

Added new MoveBelow and AlignTops overloaded methods to TCtrlArranger.

Reverted all changes made to USearch in r1883, except for copyright date and TODO item. This was done because revised implementation of nested searches in UQuery (see r1889) makes these changes to USearch unnecessary.

Re-implemented code that records and re-applies nested or refined searches. Previous implementation at r1884 was seriously buggy.

XMLDoc commented unit.
