[typo] recent comments sidebar plugin

[Matt Rose]

Has anyone done this?  I was just perusing my database directly for  
comments, and thinking.  Damn, there must be an easier way.  And then  
I thought of a sidebar plugin.  I haven't written one since my planet  
plugin was *way* too slow. I pretty much have the rails code in my  
head for it right now, but I'd hate to re-invent the wheel.  Maybe  
this'll get me to upgrade to 5.0 finally.
