[nem-en] SQL macros (dataSqlClient.n)

[Kamil Skalski]

I made some changes, to dataNpgsql and dataSqlClient.n so they now
differ only on the Helper class. Now it is possible to move even more
code to common Tools class in Nemerle.Macros

That's great, I will try this out, since I currently work on
application using sqlite3

I think chosing DB provider by switching referenced assemblies should
be possible - we have the assembly level macros, which can be defined
separately in different macro libraries. Such macro could probably
prepare and register in some global field the helper object, which
would implement creation of connection, command, parameter objects,
etc. specific for DB.
