A getting started guide for new members joining this list/group

[Martijn Verburg]

Hi all,

There's been some new subscribers and so I thought I'd repost the link to
the home page which contains a useful guide on how you can get up to speed
and best contribute:

http://openjdk.java.net/projects/valhalla/

Unless there are any objections I'll likely ping this around every couple
of months or so.

Cheers,
Martijn
