Status in duplicity - Bandwidth Efficient Encrypted Backup: In Progress

Bug description:
OK, this add support for creating par2 recovery files for every file that gets uploaded to the backend.

- can be enabled by passing --par2. If the backend already contains par2 files there is no need to pass the --par2 option.
- the par2 files are created just before the upload of the file so this will not break the asynchronous mode.
- all par2 files are preserved in the local cache and uploaded to the backend.


todo:
- add comments and logging
- add support for customizing the pa2 options currently 20% redundancy is used which might be an overkill or too little for someone
- don't use os.system and add error handling.
- add support for recovery.
  
Code review will be greatly appreciated. There are some very ugly hacks with temp files
