Convert aliases monday and sunday to methods

A recent change to beginning_of_week and end_of_week added an argument
that can be used to specify the week's starting day as a symbol. Now
these methods were aliased as monday and sunday respectively which as a
consequence of the argument addition, made calls like obj.monday(:sunday)
possible. This commit makes them methods on their own.
