Changes:

- Allow client to specify whether to encrypt outgoing file.
- Added encryption support (Blowfish). By default, all private files are compressed and encrypted before sending out.
- Added compression (based on GZIP compression stream)
- Rewrite SWP (sliding-window-protocol) to support future compression/encryption on the fly (these features make the filesize indeterminable from the beginning, hence the rewrite to accommodate).
- CLI app: add start up script for linux (see file dsl in root)
- Core Service Impl: when querying for file, if the given file name is empty, peers wil return a list of all files belong to the requesting peer.
- Core Service & Swing demo: add support to download (request file) from multiple sources.
