New check box in the Find and Replace dialog for Scintilla editors. The
new option uses the feature in QScintilla for finding text in the
selection only.
The implementation has been changed to use findFirst(InSelection) and
findNext so it works exactly as designed by QScintilla. Consequently the
finding process has to be cancel whenever any of the parameters have
changed.
A classic Find/Replace dialog including all the options provided
by the QScintilla editor. Additionally a "Replace All" and a
Find All" button are implemented. This complements issue #191
New shortcut in main window for opening the find/replace dialog
connected to the focused widget. Standard for Replace is Ctrl+H.
Consequently the shortcut for Copy with Headers is changed to
Ctrl+Shift+C (see issue #1058).
For SQL text widgets not embedded in the main window, the standard
shortcut cannot be enabled, otherwise it conflicts with the main
window. Therefore the shortcut Ctrl+Shift+H is enabled for all the
SQL widgets as fallback. A better solution would be desirable.
