Change word-break to break-all for the view-source table 

Previously, the view-source table used the UA stylesheet value for
word-break, which was break-word. This, combined with the prior
quirks-mode view source document, was a very slow Layout path.
With this change, the view-source table is set to break-all, which
should be faster. Long lines are now broken at the edge of the
page, rather than on word boundaries. So the display is different
than before. However, the content is the same, so this should
be ok.
