(describe-property-list): Don't treat syntax-table

specially.  Use describe-text-sexp which inserts [show] button
for large objects and handles printing errors.  Sort properties
by names in alphabetical order instead of by value sizes.
Add `mouse-face' to list of properties for `describe-face' widget.
(describe-char): Mask out face-id from 19 bits of character.
Print face-id separately.
