Intelligent chunk selection

With Intelligent Chunk Selection users exchange informations about which chunk is being downloaded at the moment, then a user can choose the less-downloaded (priority: spread the file faster).

Abbreviation: ICS.

In ICS the user preference "first/last chunk" catches only when there are no rare chunks (priority: spread the file).

In release mode, the shortest-to-complete chunk that is not being downloaded at the moment by any other client is selected.

This increases the probability you and the other clients download different chunks and keep (globally) a complete source for the file, even if a couple of sources become unavailable.

• You get a detailed view of parts spreading with double click on file in shared files window

There are three possibilities:

• RELEASE: complete sources <= 3: priority to upload/download the rarest chunks
• SPREAD: complete sources between 4 and 10: small chunks first, rare chunks later
• SHARE: complete sources over 10: normal behaviour (ECS or first/last)
