Minor gains

The Rdbadmin utility has been upgraded again.  I improve it from time to time, and sometimes I write aobut the changes.

A bug-fix corrected the problem that dropped schema names from function identifiers.  This proved to be a problem in managing the log trimming functions for our sql logging facility.

We also added comment displays to all the items of the table structure display, including indexes and constraints.  Only the table structure edit tool facilitates adding comments, but comments can be added to anything using SQL, like:

COMMENT ON INDEX idx_name IS 'this index is the primary key';

We have been adding comments to tables and other resources that Rdbhost creates in user accounts; When you go exploring existing tables using Rdbadmin, the comments displayed will help you, hopefully, understand how each resource was intended to serve.
