- added NETWORK_WIDE flag to remote dir model download

- added file priority strategy based on which files are requested first. This provides:
	- equal file speed for files with equal (source,priority)
	- effective priority speed for file of same source but different priority
- removed state variable load/save from turtle, as it's not needed anymore (FileRequest re-opens tunnels as needed)
- manage availability per peer instead of per file type: direct peer ids always assume file availability, while turtle tunnels don't

I still need to make the download queue work, and code this gui for it.
