Add sleep as a test suite function
This adds a class of test suite functions that are only available when a
command line switch is passed to couchjs. This so that the JavaScript
test suite has access to some helpful additional functions that aren't
part of the JavaScript language.
This particular change only adds a single `sleep` function which takes a
single argument as the number of milliseconds to sleep.
