select(*).from(table)

[sviezypan]

This PR introduces long awaited feature

select(*).from(table)

Known limitations:

• does not work with joined tables e.g. select(*).from(users.join(orders).on(customerId == id)
• does not work with more than 22 columns. In order for this to work we would need a macro. Macro would needs access to SelectionSet, however macro needs to be compiled before the call site (sql.scala), which inherits select module (which contains SelectionSet). We can make it work but we would need to re-architecture whole core module in a way that it would not have modules anymore.

Also the TrailingUnitNormalizer class which was flattening tuples is now a macro. This makes possible to flatten also nested tuples which have more bigger than 22 elements.
