Archive Mixminion-* tasks

We should archive the tasks belonging to the Mixminion-Server, -Client, and -Other components. I talked to Nick and he said he's fine taking them out if they're archived and available somewhere (with a not yet specified definition of somewhere). It looks like the three Mixminion-* components are the only components we're not likely to do any work on in the future.

Is there an easy way to export tasks belonging to these three components?

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
