- Oracle reflection of indexes has been tuned so

- Oracle reflection of indexes has been tuned so
that indexes which include some or all primary
key columns, but not the same set of columns
as that of the primary key, are reflected.
Indexes which contain the identical columns
as that of the primary key are skipped within
reflection, as the index in that case is assumed
to be the auto-generated primary key index.
Previously, any index with PK columns present
would be skipped.  Thanks to Kent Bower
for the patch.  [ticket:1867]

- Oracle now reflects the names of primary key
constraints - also thanks to Kent Bower.
