TextEditor example: allow setting multiple font attributes

When a user activates the boldAction for example, the code was replacing
QTextCharFormat's font with a default-constructed font that has the bold
attribute set, which meant that it could not be bold, italic, underlined
struck out, and with a custom size and color at the same time. On the
other hand, when we do it the current way:
  textArea.cursorSelection.font.bold = checked
we call QQuickTextSelection::font(), QFont::setBold(), and then
QQuickTextSelection::setFont(). (QFont is a QML value type, so it's the
only way.) Perhaps at some point, something was going wrong with that,
but it seems to work now.
