Compatibility with older servers that support #rewind.

[olleolleolle]

This PR is an experiment to make slack-ruby-client able to be used with Webrick via rackup gem.

The "rewind-read-rewind" used here:

slack-ruby-client/lib/slack/events/request.rb

Lines 39 to 47 in 9e6d117

	def body
	@body ||= begin
	input = http_request.body
	input.rewind
	body = input.read
	input.rewind
	body
	end
	end

...is no longer supported.

This change is about making the code compatible with older servers that offered rewind.

If you don't .rewind you end up with incorrect data, don't you? I think we need an integration test for the various servers at the very least before changing this.

Coveralls is being annoying re-running on every commit... maybe you know how to turn this off?
