* The upload functionality consist of three elements
* 1) A <div> tag with a) an optional filename of an earlier uploaded file plus and b) a trash Button.
* 2) The 'browse' button (<inputtype='file'name='_upload_<feName>'>). This element will not be send by post.
* 3) A HTML hidden element with name=<feName> containing the <sipUpload>.
* A new uniq SIP (sipUpload) will be created for every upload formElement. These 'sipUpload' will be assigned to the browse button and to the delete button.
* The individual sipUpload is necessary to correctly handle multiple simustaenously forms when using r=0. Also, through this uniq id it's easy to distinguish between asynchron uploaded files.
* The SIP contains the '_FILES' information submitted during the upload.
* Via the hidden element <feName> 'save()' access the form individual upload status informations.
Upload to server, before 'save'
...............................
* If a user open's a file for upload via the browse button, that file is immediately transmitted to the server. The user will see a turning wheel during the upload time.
* On success the 'Browse; Button disappears and the filename plus the delete button will be displayed (client logic).
* The uploaded file will be checked: maxsize, mime type, check script.
* The uploaded file is still temporary. It has been renamed from $_SESSION['X'][<uploadSip>][FILES_TMP_NAME] to $_SESSION['X'][<uploadSip>][FILES_TMP_NAME].cached
* The upload action will be saved in the user session.
* In the usersession a flagDelete will be set: $_SESSION['X'][<uploadSip>]['flagDelete']='1'
* An optional previous upload file (still not saved on the final place) will be deleted.
* An optional existing variable $_SESSION['X'][<uploadSip>][FILES_TMP_NAME] will be deleted. The 'flagDelete' must not be change - it's later needed to detect to delete earlier uploaded files.
Form save
.........
* Before building the insert/update, process all 'uploads'.
* Get every uniq sipUpload to every upload formElement. Get the corresponding temporary uploaded filename.
* If $_SESSION['X'][<uploadSip>]['flagDelete']='1' is set, delete prefious uploaded file.
