[Squirrel-sql-develop] Feature Patch: hierarchical table view

Hi,
For a little project of mine (some object mapping database) I implemented
a JDBC-Driver that can return the hierarchy of tables with the
 DatabaseMetaData.getSuperTables().

I don't know, if there is any database out there, that already supports
this feature of recent JDBC (even though some object-oriented databases
might have it), but just in case someone is interested in this feature, I
extended the tree-view of the Database-objects of squirrel in a way,
that the hierarchical stucture of tables is represented as tree as well.

In the normal case (e.g. if DatabaseMetaData.getSuperTables() of the
driver does not return anything or is not implemented) this does not make
any difference, but if it returns something, the tables are shown as tree.

See attached patch; I'd be happy to see it included :-).

ciao,
 -hen
