Added proper dl queue behavior

- suppressed old DwlQueue class
	- turned mDownloads into a list of pointers to allow easy cross-info update between queue and std::map of downloads
	- added queue functionality for moving files top/bottom/up/down
	- added the necessary functions in rsFiles

Put back display of exact sizes in FileTransferInfoWidget

Suppressed some warnings.

**Warning**: this commit requires a make clean.
