Code improvement : Images, Files and Upload Classes

The php classes managing the files has been entirely rewritten.
It is now clean and consistent !
Now, only one helper file is handling all the work for upload, thumbs, :
HelperFile : (helpers/file.php)

The following files has been removed :

classes/file/file.php
Has been renamed in a helper, because it is a static class, so its place is in the helpers.

classes/file/upload.php
Has been merged inside HelperFile. It still does the same job with few improvements at the level of the caller.

classes/images.php
Has been totally removed and the work is left to the JImage native class of Joomla!
We don't need anymore with the actual version of Joomla!

classes/image/image.php
Has been removed because it was an empty class file.


A new important function appeared in the item controller: updateFileField()
It manages the uploader call, manages the file / thumbs deletions and update the image value field in the database in only one static call.

REVIEW YOUR FORKS !
In case you have forked and called one of those classes on your forks, you need to update your code !

Make a search in your forks about thoses classes :

• [Xxxx]ClassFile
• [Xxxx]ClassFileUpload
• [Xxxx]ClassImage
• [Xxxx]Images

Entry point

[Xxxx]ClassFile::returnFile('db');

becomes:
[Xxxx]HelperFile::returnFile();

$model->_upload('photo', array(
         'image/bmp' => 'bmp',
         'image/gif' => 'gif',
         'image/jpeg' => 'jpg,jpeg',
         'image/png' => 'png')
     , array(
         'rename' => '{ALIAS}.{MIMEXT}' 
     )
 );

becomes:

self::updateFileField($model, 'photo', array(


    'rename' => '{ALIAS}.{MIMEXT}'

));
