suggestion: prevent "Add video" button from being clicked during uploads

[scharnkn]

On the "Add video screen" it is currently possible to click on the "Add video" button while there are video uploads in progress. Doing so (e.g. by accident) will interrupt the current uploads, which can be a problem especially with large files and slow internet connections.

Two ideas that might help:

• Gray out the 'Add video" button during uploads and provide another means of cancelling uploads, e.g. a red cross next to the progress bar
• Change the text of the "Add video" button to "Cancel uploads" (or something similar) during the uploads

Adding video here in moodle opencast plugin happens syncroniusly, which means that you could perform add videos as many time as you want but a scheduled task is responsible for upload, therefore, this suggestion is not compatible with the current way of doing upload. (General)
(UPDATE) in case of uploading large of with slow connections, the scenario is not covered and must be taken care of!
