Rename jsonb_replace to jsonb_set and allow it to add new values

Browse Source 
The function is given a fourth parameter, which defaults to true. When
this parameter is true, if the last element of the path is missing
in the original json, jsonb_set creates it in the result and assigns it
the new value. If it is false then the function does nothing unless all
elements of the path are present, including the last.

Based on some original code from Dmitry Dolgov, heavily modified by me.

Catalog version bumped.
