[LorisForm] Fixing the loris form '0' emptying issue (aces#2781)

$this->form->addRule("value", "Required", 'required'); sets the 'required fail' when the user submits a value of "0", because empty($value) is true for 0.

This updates the code to explicitly check for the empty string to detect no input, and avoids PHP's empty() function for validation.

This reverts commit 1bf483f.

The addition of the parameter "minc_location" parameter added by this commit introduces
a severe security hole, where user input is getting passed directly to the PHP
passthru command.

attempting to login in order to prevent the login page from returning
a 403 on first access.
