Add function Form::saveFile()

This is a rework of how the framework handles performing file uploads.
Rather than attaching new fields to a form (of type file) and handling
them during populate() then saving later, users can call what is
essentially a static function and save files in isolation.  Since each
webform I can conceive using in Scrott at this time won't be uploading
more than one file at a time, this model should work nicely moving
forward; however can be easily adjusted if need be.
