MT 2.6 test entry

Testing MT 2.6.

Update: So far so good!

Update 2: I lied. We're going back to 2.51. It appears that encode_xml="1" is broken in the RSS feeds and that's just no good. I'm bummed.

Update 3: Speedy replies on the MT forum! Ben & Phil both have suggestions that I'll try out tomorrow on a standalone blog. Phil posted a hack to Context.pm that I'd be fine making.
