New look and new features on the SEA website

SEA website has been updated both in look and content. Thanks and kudos to Jeff Alipit for his help.

Now the website is easier to navigate, there is a blog, and yes, Si has started fostering Knowledge Sharing with the forums, where people can discuss Software Engineering topics, such as Fortran, Parallel Programming, Seminar subjects, Q&A, or simply post their suggestion about the last great thing they've seen.

I encourage the few of you who posted this kind of messages on the mailing list, to re-post them on the appropriate forum, where they can more easily found for future reference (and discussed by the interested group without fear of spamming dozens of people's email).
