For early adopters: [[bzero]] v0.12 is here. Tell me if it works :-)

To make things a little more visible, the README is now online.

Changes:

• Post-by-email implemented; use ‘bzero checkmail blogname’ to check a POP3 account and post messages (with a valid secret word in the subject) to a blog.

• New command ‘bzero editlast blogname’ brings up the most recent post in your editor.

• More useful errors produced when the community server does something odd.
