- Implemented chunk-based file transfer from partial sources. This in particular means:

- 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
