Summary: specialcase simple sliceobj in list (and bugfixes)

Initial Comment:
 - Specialcase the step=1/None case of slicing using sliceobjects.
 - Fix bug where slice insertion using a sliceobject was inserting in a different place than slice inserting using a simple slice
 - Fix two off-by-one bugs that were cancelling each other out: the non-step-1 slice deletion code was memmoving too much for each item to delete, and not enough for the tail end, net result being a few too many bytes moved for each item.
 - Rewrite tail end move when deleting complex slice, use single memmove() instead of repeated PyList_SET_ITEM()
 - Expand comments describing the code somewhat.
