Global upload options provider shared by all uploader plugins.

## How to change the upload limit?

Upload size is limited by PHP configuration. Thus, by default, this plugin can only lower the original php.ini value. You cannot simply raise the configuration here, you have to change the php.ini value by a way or another (php.ini file, .htaccess php_value key). The following parameters must be updated :

- post_max_size
- upload_max_size

Once updated, restart your webserver (Apache for example) to make sure the configuration is taken into account, then in this configuration panel, set the "File Size" parameter to 0 and save. Re-open the panel, you should see the php.ini value reloaded.
