Fix singlePar update. This should result in a nice speed improvment for Mac.

* buffer.h: changed() signal now emit a singlePar boolean.

* WorkArea::redraw(): acknowledge singlePar changed() boolean

* LyXView.C: adapt signal connection to changed() signal change.

* lyxfunc.C: transmit the singlePar flag with the Buffer::changed() signal.
