pgAdmin III commit: Fix inherited columns for multi-inherited table

Fix inherited columns for multi-inherited table

Tables with multi inheritance would get lots more columns than they really
have (number of columns times number of inherited tables). This patch fixes
this behaviour, making sure we have only one time a column.

Fixes #279.
