Revamp and expand news handling

A number of improvements and unifications for news:
* News posts now get authors

* Authors are from NewsPosterProfile:s, which will include a full name
  and an "urlname"

* Authors can also be specified as "can post global", which should
  give rights to post on the global feed. Right now the global feed
  requires superuser access anwyay, but for the future...

* News can now be posted at conference level as well as previous
  global only

* Front page of website pulls in a combination of global news and
  conference news. Global news can be given a "high priority until"
  field that ensure it sits at the top of the frontpage until a
  certain date, so conference news can't push it off.

* Each conference gets it's own RSS feed. This one is also available
  via JSON for an easy way to pull it into the conference site itself.

* All links to posts in the conference feed goes to the conference
  homepage. It's really only designed for transient news.

* Each user also gets it's own RSS feed. This is designed so that it
  can be submitted to an aggregator like Planet PostgreSQL which
  requires personal feeds. Conference specific news are automatically
  prefixed by conference name.

* Each post can individually be toggled if it should be included in
  the RSS feed or not

* Re-adds the news archive, with a paginated view

* Each post can individually be toggled for inclusion in the news
  archive, so it's possible to create more transient news. News
  archive *only* contains news from the global feed, not the
  conference feeds.

* Makes the "read more" button on the frontpage only show up if the
  entire news post did not fit
