DESC[RIBE] for MSSQL

The package contains two T_SQL procedures: sp_desc and sp_desc_more.
Both of them are like the DESC[RIBE] command in SQL*Plus.
These can be useful for those who are accustomed to DESC[RIBE] command in SQL*Plus.
The two variants, sp_desc and sp_desc_more, are suitable to describe TABLES and VIEWS.
Outputs are similar to the output of the SQL*Plus DESC command, there are just some differences:
both of them show the auto-increment (IDENTITY) primary keys, moreover sp_desc_more shows object
comments and all references, too. (See sreenshots.)
