889a2b2433 Added deferred check of chunks during file transfer. Chunk sha1 sums are requested to the sources and checked for downloaded data.
Validated chunks are shared to other peers. Force check is now very simple since it just turns all chunks into "needs checking" mode
and sums are asked to sources. Sources maintain a temporary cache of chunks. Since sums are requested sparsely, this should not 
affect the sources in terms of performance. We can still imagine precomputing and saving sha1 of chunks while hashing them.

For backward compatibility reasons, the following has been setup *temporarily* in this version:
- unvalidated chunks are still considered as already obtained, and are shared and saved
- force check has been disabled
- final file check is maintained
- in case of file fail, the old checking mode will be used.

All changes for next version are kept in the define 'USE_NEW_CHUNK_CHECKING_CODE' that will be made the default in a few weeks.
At start, I expect most chunk to stya yellow during download, until most sources are able to provide chunk hashs.

de217179d3 additional info into FileTransferInfoWidget

506f14eb2f - Added a parent page widget (class RsAutoUpdatePage) to handle auto-update. The page updates using a timer, only wh
en visible, and each time it gets showed. I already made some RS pages derive from this page.
- Modified and renamed the taskGraphPainterWidget to display info about currently selected file transfers. For know, it only shows file chunks info, but we should use it to display additional info about the transfer. Warning: in its
 current state, only fake chunk info is displayed.
 - Suppressed p3files.h, because it is not used.

 Remains to do (in order):
 - Implement a chunk map class in ft/ to properly manage which chunks should be downloaded 
 - Display correct chunk info by requesting the transfer's chunk map
 - Add check-sum verification of chunks
 - allow RS to import a partially downloaded file by force re-checking chunks
 - Add chunk map exchange from file source peer id to file destination peer id.
 - Manage chunks from different peers.
 - Allow search (turtle search) for partially downloaded files
