fix: passing the table DB name to the enum-generation steps (gnormal#98)

This changes allows to use the table name while generating file names or struct
names (in Go) for enums, which may help avoid name collisions (2 tables might
have 2 different enums but with the same column name).

Also: updated the dependencies with dep ensure.
