Patch to make belongs() a little nicer

[Michael Toomim]

This patch lets you use belongs() with fewer parentheses. Instead of having to type:

field.belongs((1,2))

You can now use:

field.belongs(1,2)

It's backwards compatible. Any objections? Can this go in trunk?

To make this more concrete, it lets you run:

db(db.scheduler_task.status.belongs('QUEUED','ACTIVE')).select()

instead of

db(db.scheduler_task.status.belongs(('QUEUED','ACTIVE'))).select()
