News: updates and corrections

'Local news' becomes 'FreeBSD Project and The FreeBSD Foundation'.

Conciseness.

Remove bsdtalk. The most recent recording is more than five years old.

There remains only one podcast. Comment out the 'Podcast' heading.

The BSD Now podcast becomes uppermost of the other sites, with bullet
points edited by one of the hosts.

Remove FreeBSD Diary. Instead: Dan Langille's Other Diary.

Link to two Phoronix areas.

Make the OSNews link FreeBSD-specific.

DaemonForums, not Daemon Forums. https, not http. Make the link
news-specific.
