Release Name: 0.2.3

Notes:



Changes:
This is mostly a bugfix release. Work on new features and a better UI is
taking place in the 0.3 branch at the moment.

* critical workaround for a modification in ostruct.rb introduced
  recently in Ruby's ruby_1_8 CVS branch and HEAD (1.9), which broke
  rpa-base altogether. Note that this workaround was released as a
  self-update, but people using recent 1.8 builds (including the latest
  preview) would not be able to install rpa-base for the first time

* support for
    rpa install package1.rpa .... packageN.rpa
  (you can copy the binary packages built on one machine to another and
   install without a connection to the Internet)

* rpa update doesn't limit the new/updated info to the last 14 days

* bash completion script included (thanks to Brian Schröder, Nobu Nakada)

* several minor bugfixes
