Euphoria Ticket #508: std/utils.e should have all_equal()

This would be an easy way to compare all elements of a sequence.

Single element sequences would return true (an element will equal itself) and the empty sequence also returns true. 

public function all_equals(sequence s) 
	for i = 1 to length(s) - 1 do 
		if not equal(s[$],s[i]) then 
			return 0 
		end if 
	end for 
	return 1 
end function

A potential workaround / implementation: 

not length( find_all_but( my_seq[1], my_seq, 2 ) )

Note that this doesn't check for an empty sequence.
