Map underscore to camel case for SqlColumn objects

When I query data with CommonSelectMapper.selectManyMappedRows() method, it can't map underscore to camel case automatically, I have to specify an alias for every cloumn, I think we can do something to improve this.

The way I can think of is to add a method like asCamelCase for SqlColumn class, which can convert the name of the column to camel case, and return a new SqlColumn object, what do you think?

Thanks - I think this is a good idea. I'm doing some experimentation with it, then will commit something.
