[ldelcano]

Virtual Folder integration on SWT.

Write Disvis developers to ask how they have done it.

[ldelcano]

Already integrated a first version. Added a tab on the uploads window for 'VRE upload'. If the user is logged to the VRE SSO it will open the VRE filepicker and user can select a file to be uploaded to SWT server, and then choose it as an entry for protocols. If the user is not logged it should open the SSO page to login.

Added an animated GIF to load while uploading file.

Also, add 'Download results' to VRE.
