- exchange of chunk availability maps from different peers
- correct handling of what is available to which source before asking the data
- correct display of chunks in the progress bars
- generalised the use of compressed chunk maps
- removed the size parameters from the hash search functions
- In addition:
- suppressed a number of per-value transfers of std::string
- improved the FileTransferInfo Widget, to show some additional info
Still to be done:
- chunk map exchange for non anonymous traffic (easy)
- improve accuracy of completion for uploads (for now it's a integer number of chunks)
- check compilation on windows
