Here's a patch. It adds the needed shell command implementation and modifies HBaseAdmin, HMaster, HMasterInterface to add the needed modifyColumn method.

> Right now, you can add or delete column families, but not change them once they are created. This is really inconvenient for things like adding compression or bloom filters to a column family once you get going. As new people come to HBase, they're going to make schema decisions that are incorrect and will need a way to modify their tables, so this is an important new feature.
