Hi Jon:

For CJK site bayesian filter does not work well, but I believe it works well for western user. The problem is not in Bayesian Fitler it self, it is becasue the tokenize().

Esepecially, if we ask BayesianFilter to learn what is the spam from the comment text and topic. 

I am not sure you can see Chinese or Not, but here comes the example:

我是一個程式開發者 <== Means "I am a developer"

In english, you can easily seperate the sentense just by seperate them by white space, but in CJK, we can't. The whole sentense should seperate to

我(I) 是(am) 一個(a) 程式開發者(developer)

It is about the natual language process. It is the most default part.

It is a side topice, that's why I said "For your information"

I will keep your commit in 1.2, it seems we already have a conclusion to do this way.

But, I will try to implement the $filter order or say priority in 2.0.

So, we can make sure the bayesian fitler can run in the last minutes and user can have chance to unmark them.
