Bug 1293739 - Part 1: Rename nsCSSProperty to nsCSSPropertyID. r=dholbert

This patch is generated by the following commands (note: if you're running
using OS X's sed, which accepts slightly different flags, you'll have to
specify an actual backup suffix in -i, or use gsed from Homebrew):

  hg stat -c \
  | cut -c 3-  \
  | tr '\n' '\0' \
  | xargs -0 -P 8 gsed --follow-symlinks 's/\bnsCSSProperty\b/nsCSSPropertyID/g' -i''

Then:

  hg mv layout/style/nsCSSProperty.h layout/style/nsCSSPropertyID.h

... and finally, manually renaming nsCSSProperty in the include guard in
nsCSSProperty.h.
