preserve header comments when reading/writing model files
experience is deprecated and removed from Itself model
removed obsolete permission attribute (breaks test with C::M >= 2.056)
min and max parameter accepts number...

Acepting integer is too restrictive for value_type number. One could
warp (meta) value_type of min and max depending on value_type value,
but it's a lot of trouble just for this.
config-model-edit: use Path::Tiny instead of Path::Class
removed use namespace::autoclean (drags Moose)
refreshed dist.ini. added auto-prereq
removed usage of AnyEvent (requires C::M 2.055)
dist.ini: added missing skip in AutoPrereqs
Fix pod doc for Pod::Weaver

    Main change is the deprecation of the experience attribute.
    config-model-edit can be used to clean up experience parameter
    from existing model.

    Dependency changes:
    * removed usage of AnyEvent (requires C::M 2.055)
    * removed use namespace::autoclean
    * config-model-edit: use Path::Tiny instead of Path::Class

    Other changes:
    * min and max parameters accept number.
    * removed obsolete permission attribute from test models
      (which broke test with C::M >= 2.056)
    * preserve header comments when reading/writing model files
    * config-model-edit begins with "#!/usr/bin/env perl"
