Omit needless words: give initial Boolean parameters argument labels.

When the first parameter of a function has Boolean type, try to create
an argument label for it. We start with the (normally non-API)
parameter name as the argument label, then try to match that against
the end of the base name of the method to eliminate redundancy. Add a
little magic, and here are some diffs:

    -  func openUntitledDocumentAndDisplay(_: Bool) throws -> NSDocument
    +  func openUntitledDocument(display _: Bool) throws -> NSDocument

    -  func fontMenu(_: Bool) -> NSMenu?
    -  func fontPanel(_: Bool) -> NSFontPanel?
    +  func fontMenu(create _: Bool) -> NSMenu?
    +  func fontPanel(create _: Bool) -> NSFontPanel?

    -  func lockFocusFlipped(_: Bool)
    +  func lockFocus(flipped _: Bool)

    -  func rectForSearchTextWhenCentered(_: Bool) -> NSRect
    +  func rectForSearchText(whenCentered _: Bool) -> NSRect

    -  func dismissPreviewAnimated(_: Bool)
    -  func dismissMenuAnimated(_: Bool)
    +  func dismissPreview(animated _: Bool)
    +  func dismissMenu(animated _: Bool)
