Crash on 2GB File Transfer

[zachongit]

I just watched a 2Gb file get to 99%, then the receiving Diode Drive client crashed. This happened twice in a row (with the file starting back at 0% between). May be related to #110

I guess memory is currently on receival 3x occupied. E.g. for a 2Gb file there are 6Gb of memory consumed. 1) The file as it's being received in fragments 2) The fragments joined together 3) The resulting binary decompressed. To change this we need to change the sync protocol to make the downloads aware of an additional splitting into file chunks. The chunks (e.g. 1mb per chunk) can be stored on disk and retrieved from different peers each (like bittorrent). Then once all chunks have been received the file is being joined & extracted
