If the $_SCROTT['AUTO_MODAL'] global is defined, it will refer to a
modal's DOM ID to be shown once the page loads.  Currently, an error
state will supersede this and display the notice modal instead.

Removing these unnecessary checks.  They are not protecting us from
anything, only inconveniencing me in index.php.

This is an alternative function to globals' saveFile(), which allows
model code to just pass in the name of the expected uploaded file,
rather than requiring them to look up the file themselves.  This is in
line with my preference to encapsulate PHP superglobals access away from
most of the codebase.

Note that even if the user opts not to upload optional files, the
associated file <input> field will still be present in $_FILES, with a
special error code set (meaning 'no file uploaded') which setFile()
ignores.  It is only in the case of a malformed form submission that
$_FILES will be missing the requested file field, prompting Scrott to
throw an exception.

The initial intended use case for this is applying the "active" and "in
active" classes to the first tab to appear in the settings modal.

The intention is for index.php to set this variable.  This is the text
(HTML) displayed on the button for the pad select dropdown in the nav
bar.  Basically the canonical name of the page we're on.
