Allow composer packages and the root json to disable helper functions
Allow composer packages and the root json to disable helper functions

This tweak basically lets the init go up the tree a ways
attempting to find a composer install. If any of the installed
packages or the root composer.json contains a truthy field
"extras.kint.disable-helper-functions" kint will not attempt to
create the d() and s() functions.

While you could always disable them by initializing them yourself
before the composer autoloader started, this allows a nicer and
more explicit way to disable the helper function initialization.
