Update to 2.1600

Upstream changes:
2.1600   2015-07-31

  [DOCUMENTATION]

  - Made all docs use =head2 and =head3 for methods/functions so that they
    appear as part of the table of contents on MetaCPAN.

2.1501   2015-07-20 (TRIAL RELEASE)

  [DOCUMENTATION]

  - Added a new slideshow by Shawn M. Moore (sartak) to
    Moose::Manual::Resources
  - Documentation for exception classes has been rewritten, with
    Moose::Manual::Exceptions::Manifest changing how it describes each class's
    attributes and methods. (Dave Rolsky, PR#95)

  [REVERSIONS]

  - The change in 2.1500 to allow DOES to check delegated options has been
    reverted. This turned out to have a variety of issues both in concept and
    implementation; it will be refined further in MooseX::Does::Delegated.

  [CHANGED]

  - The name for an anonymous sub that is used in method modifiers (that shows
    up in stack traces etc) now identifies the package and method being
    modified. (Philipp Gortan, PR#94)

2.1500   2015-07-01 (TRIAL RELEASE)

  [ENHANCEMENTS]

  - An object's DOES method now also checks roles composed by delegated
    objects (Chris Prather, PR#104)
