Support alias for parent table

[miellaby]

When joining tables, NotOrm knows how to put an alias on a joined table if its "public" name differs from its real table name (because of a user customized structure). Columns are then correctly identified by "$name.$column" string ($name actually being the alias).

But it doesn't work for the parent table.

I tried to set up a user structure so to add explicit non-defaut database names on a couple of tables. createJoins works if these tables are refered in select. It doesn't work if the parent table itself is non trivial.

I patched my NotOrm copy for my specific needs. But I feel like it's a more general issue. Result objects may have distinct "name" and "table" attributes so that sql buiding could alias the parent table in the same way than joined tables.
