Turn white-space into a shorthand

[Loirooriol]

Split it into white-space-collapse and text-wrap-mode:

white-space	white-space-collapse	text-wrap-mode
normal	collapse	wrap
nowrap	collapse	nowrap
pre-wrap	preserve	wrap
pre	preserve	nowrap
pre-line	preserve-breaks	wrap
-	preserve-breaks	nowrap

Note this introduces a combination that wasn't previously possible.
