Advanced F&R rework:

- scopes now handled in FindAndReplaceWidget, while lyxfind.cpp only searches within single buffer
- cursor().result().dispatched() now encodes whether a match was found or not, after LFUN_WORD_FINDADV dispatch
- removed a few unneeded functions
- followed a few cosmetic advices
