Conversion to www.mattmetzgar.com

Originally, this blog was setup as mattmetzgar.blogs.com, and the domain name www.mattmetzgar.com forwarded to that address.  I've now enabled "domain mapping", so that www.mattmetzgar.com should show up in the address bars of all posts. 

This is just a change to make everything cleaner and simpler.  The old mattmetzgar.blogs.com and all the old links should still work fine.  There may be some temporary disruptions, but everything should be sorted out in the next day or two.
