Add a top() fluent function

[briancampo]

Absolutely loving the simplicity and straightforward nature of the project. Thank you!

Would love to see a .top(xxx) function added. This would formulate the TOP clause for the sql.

I'm willing to settle ;) for LIMIT as well if that is a better option.

@briancampo we can add it. Need to search if top exists in all dialects we have right now

That would be excellent. Thanks!
