When multiple files from the phone are received a FileTransferJob for each is started. These jobs should be batched together into a KCompositejob.

Relevant modules: SharePlugin on Desktop and Android, FileTransferJob class from core
Requires research about Jobs in KDE Frameworks/KIO

Possible approach:
Each file is transferred in its own NetworkPacket, because there is only room for one payload per packet. One could either

• allow more than one payload per NetworkPacket, would require changes to NetworkPacket on both sides without breaking existing code
• add some information to the NetworkPacket to indicate which Filetransfers should be batched together
