Fixed following issues for 1257:

1. For synonyms, the property is shown as "Public Synonym".
 2. For system procedure, the flag should be True but it is displaying as False.
 3. For both views and materialized views, the property is "System View".
 4. For FTS templates, the property is showing as "System FTS Parser".

Fixes #1257
