    * New /configupdate.jsp page for controlling the update / notification
      process, as well as various minor related updates.  Note that not all
      options are exposed yet, and the update detection code isn't in place
      in this commit - it currently says there is always an update available.
    * New EepGet component for reliable downloading, with a CLI exposed in
      java -cp lib/i2p.jar net.i2p.util.EepGet url
    * Added a default signing key to the TrustedUpdate component to be used
      for verifying updates.  This signing key can be authenticated via
      gpg --verify i2p/core/java/src/net/i2p/crypto/TrustedUpdate.java
    * New public domain SHA1 implementation for the DSA code so that we can
      handle signing streams of arbitrary size without excess memory usage
      (thanks P.Verdy!)
    * Added some helpers to the TrustedUpdate to work off streams and to offer
      a minimal CLI:
          TrustedUpdate keygen pubKeyFile privKeyFile
          TrustedUpdate sign origFile signedFile privKeyFile
          TrustedUpdate verify signedFile
