Same treatment as listobject.c:
- In count(), remove(), index(): call RichCompare(Py_EQ). - Get rid of array_compare(), in favor of new array_richcompare() (a near clone of list_compare()). - Aligned items in array_methods initializer and comments for type struct initializer. - Folded a few long lines.
