* The file upload code uses several hooks to interact with blueimps jQuery file upload library:
|
|
* 1. the core upload handling hooks are added when initializing the plugin,
|
|
* 2. if the browser supports progress events they are added in a separate set after the initialization
|
|
* 3. every app can add it's own triggers for fileupload
|
|
* - files adds d'n'd handlers and also reacts to done events to add new rows to the filelist
|
|
* - TODO pictures upload button

|
* - TODO music upload button
