[dcc2] Multi headers + metadata

[Craig Edwards]

if this is the case the simplest encryption and simplest compression methods should be the manditory ones, for slower machines and small-memory machines such as PDAs etc.

e.g. blowfish as the minimum encryption type (as this has been proven to work on small-memory model and slow processors) and runlength or huffman as the basic compression type (however this would still be optional as the receiver could still say 'no thanks' to the compression and force the file to be sent uncompressed).
