* convert_content_type! is handled by assign_default_content_type_and_charset!
  * set_content_length! should be handled by the endpoint server. Otherwise
    each middleware that modifies the body has to do the expensive work of
    recalculating content_length.
  * convert_language! appears to be legacy. There are no tests for this
  * convert_cookies! should be handled by the new HeaderHash in Rack
  * Use an integer for .status's internal representation to avoid needing to
    do String manipulation just to find out the status

  * Significantly simplifies setting and modifying cache control in other areas

hashes and arrays like #find does.

Make sure we use send for the default attribute method body because the suffix maybe an invalid method name

Fix tag helpers so that all HTML element boolean attributes render according to the specs. Added all boolean attributes listed in the XHTML 1.0 specs (http://www.w3.org/TR/xhtml1/guidelines.html) and HTML 5 specs (http://www.whatwg.org/specs/web-apps/current-work). HTML 5 boolean attribute rendering was broken in commit 1e2d7229 / [#2864 state:resolved].
