Remove version from README.md

install.sh now uses `--release <version>`
Introduce initial translation support

All scripts will be translated. Gettext .mo files need to go in
linuxclientsetup/l10n in the proper directory structure.

Not translated:
 - pre-created desktop icons
  * offline home area icons
  * admin icons
 - core system
  * needs to pull down language setting from server, then install required
    language packs
