Ready to release?

[Jason Garber]

I think I'm ready to release RedCloth 4.0.  Anyone have any  
objections?  Should I tag the latest commit as RC1 or should we just  
go for it?  It's pretty much a given that with as many changes as were  
made between 3.0.4 and 4.0 we overlooked something and will have to  
release 4.0.1 in short order.

I'm sending _why the latest gems to put up on his gem server.  Once  
they're up, see if there's anything you want fixed before the release.
