Update word-wrap to overflow-wrap
overflow-wrap is the new name for word-wrap, and should be implemented to adjust to the standards.

Implemented in Firefox 49: https://bugzilla.mozilla.org/show_bug.cgi?id=955857
Already supported in Blink and WebKit: http://caniuse.com/#feat=wordwrap

As far as I understand this is just a renaming of word-wrap, without any behaviour changes.
