[gnome-db] [PATCH] support for inner queries alias without the `AS`.

[Arthur Neves <arthurnn gmail com>]

Hi folks,

I am using libgda to parse all queries on my app, however I saw that sub-queries that had an alias were not working, for instance: 

  SELECT foo.abc FROM (select abc from bar) foo;

See this is valid on sqlite3:

sqlite> create table bar(abc varchar(10));

sqlite> insert into bar values('hi');

sqlite> SELECT foo.abc FROM (select abc from bar) foo;

hi

Seems like that syntax was not handled by the parser.y lemon file. So I have a patch for it: 

https://github.com/arthurnn/libgda/commit/0ba0e8f49f90304256e4fca637928d8cad55a1e0

Let me know what is the proper way to contribute to this library, if sending a Pull Request on GitHub, or sending a .patch file on the mailing list.

Let me know if this makes sense

Thanks a lot
