* Add support for running multiple instances of openvpn to the startup script

  Inspired by [1]
* Bump PORTREVISION
* Update the comment which says not to send notices about 2.0.8 to 2.0.9 since
  2.0.9 also introduces only Windows changes. Remove maintainer's name from
  this comment since he did not explicitly state this.

Submitted by:	Denis Shaposhnikov <dsh@vlink.ru>, Gleb Kozyrev <gkozyrev@gmail.com> [1]
