Raising in equality precludes working with AwesomePrint

Second comparison of this method in awesome_print/formatter.rb causes
the crash.

Without this fix, pry + awesome_print cannot be used, as even a simple
case such as

[1, 2, 3].to_scale

will crash

    # Catch all method to format an arbitrary object.
    #------------------------------------------------------------------------------
    def awesome_self(object, type)
      if @options[:raw] && object.instance_variables.any?
        awesome_object(object)
      elsif object == ENV
        awesome_hash(object.to_hash)
      else
        colorize(object.inspect.to_s, type)
      end
    end

Prevent FloatDomainError on Histogram with span=0

If a Histogram is created with a set of equal values (e.g., [3,3,3])
a `FloatDomainError: -Infinity` error will be raised when calling
`to_svg`. This happens because the span calculated in `Statsample::Util#nice` is 0 (see stacktrace below).

It appears that the original code may have been guarding against this by
testing `!span`, but this is incorrect and should be tested as `span ==
0`. (This may have been a check against `nil` and not zero, but there are better ways
to handle that (e.g., `span.nil?`) and it also seems that span could not
be `nil` due to the lines of code immediately above, which would raise an error
if either `s` or `e` were `nil`.)
