/**
* PrsoGformsAdvUploaderInit
*
* This class adds a new custom field type to Gravity Forms called 'Advanced Uploader'.
* The new field outputs an advanced file uploader to any form based on Plupload jquery plugin.
*
* Plugin options allow devs to quickly alter advanced Plupload parameters from the admin area.
* These are then applied to all advanced upload fields in forms. Some parameters such as file size and
* allowed file extensions can be overriden on a field by field bases via the Gravity Forms field settings.
*
* File Upload Process:
* 1. Plupload uploads files to temp folder in uploads folder, filename is encrypted in DOM.
* 2. Once form is succesfully submitted then files are added as wordpress attachments in media library
* they are validated, given a randomly created filename (security measure) before adding to library
* 3. Meta data on file attachment is added to Gravity Forms entry table so that files can be displayed
* in form entry view with link to each file in media library
* 4. An option is added to entry view to allow attachments to be auto deleted when a form entry is deleted,
* although this is not required and files can stay in media library after entry is deleted.
*
* Security and Validation:
* 1. Empty index.php file is added to temp folder used by plupload in uploads dir
* 2. htaccess file is also added to folder to prevent scripts from running - see qqFileUploader.php
* 3. Both file extension AND mime type are validated when plupload attempts to save file into tmp dir
* finfo_file() is used to extract the mime type which is compared against $this->allowed_mimes which
* uses get_allowed_mime_types(); This can be filtered via 'prso_adv_uploader_reject_mimes'
* 4. Files uploaded to tmp dir by plupload have names encrypted and stored in a gravity forms input field in the dom
* file names are decrypted once the form has been submitted and the files are being processed into media library
* 5. Enryption of tmp file names in the dom should help prevent malicious code from being added and run from tmp folder.
* That said the htaccess, index.php, and mime validation should prevent that anyway.
