Summary0016172: provide a an abstraction to check if a specific type of frame is selected
Descriptioncurrently, if i want to make sure that one text frame is selected i need to do:

    if (!HaveDoc)
        return;
    if (doc->m_Selection->count() != 1)
        return;
    if (doc->masterPageMode())
        return;
    if (doc->appMode != modeEdit)
        return;

    PageItem* currItem = doc->m_Selection->itemAt(0);
    if (!currItem->isTextFrame())
        return;


it would be nice to have the high level function:

    item = doc->getSingleTextFrame()
    if (!item)
        return


they will return nullptr if the conditions in the name of the function are not met. (it would be even better if it could return a "NoItem" object)

another function would be

    item = doc->getSingleTextFrameFromPage()

which would exclude items from master pages.

for this to work, we should have a special doc that is a NoDoc (doc should never be a nullptr)

the goal is to avoid functions like ScribusMainWindow::insertMark(MarkType mType) that hide what a dialog really does, because of the boilerplate.
