Add support for multiple tables in 'from' argument for select queries.

[Danappelxx]

It's a fairly common pattern to have a join table and select all the values from the other two tables.

Goal syntax:

Select(["table1.*", "table2.*"], from: ["table1", "table2", "table1_table2"])

Current workaround syntax:

Select(["table1.*", "table2.*"], from: "table1, table2, table1_table2")

Fixed as of a while ago
