Switch to hand-rolled packaging/distro scripts

Several bikeshed reasons brought me to this point:

* I like the README.html layout more than any default index.html
  even if it's using README content.  Having links on the side
  helps navigation IMHO.

* publish_docs preserves timestamps to improve cache hit rate

* git is used to maintain the manifest at packaging/release-time
  so my changesets have less noise in them

* git is used to generate history files (from tag messages),
  this is a more DRY approach to me.

* I don't like the ".txt" suffix being translated to "_txt.html" in
  URLs.  I don't like the ".txt" suffix in general.

* I don't like Manifest.txt showing up in my RDoc
