Added basic Composer file
Removed trailing comma
Added empty classmap
Always load kyHelpers.php

kyHelpers.php contains functions used elsewhere, but since PHP won't
autoload functions we must tell Composer to do it.

We *could* autoload kyIncludes.php, since that includes every other
file, but this would just waste memory as the other files only define
classes, which PHP has no problem autoloading.
