Add TorrentHandle::availableFileFractions() function

Browse Source 
The function returns list of availability values for all torrent files.
The availability here is different to that one in the progress bar. Here
it shows what part of the file's pieces is available (i.e. we do not count
availability > 1 for a piece).
