RxFPC:patch from Iliya Iliev: 1. TRxDBLookupCombo - added protected method DoSelect - encapsulates OnSelect logic; 2. TRxDBLookupCombo - added public methods Clear & IsEmpty; 3. TRxDBLookupCombo - exposed property BorderStyle (default bsNone). When it's bsNone, nothing changed, while when it's bsSingle there are changes in Painting.; 4. TRxDBLookupCombo - changed method Paint - it respects BorderStyle property; 5. TPopUpFormOptions - added new property SearchFromStart (default false) - when it's false, nothing changed, while when it's true popup form locates the row only if it starts with the searched text.
