Need optimizations

I'm using JSON library with NETCF 2.0.
It works, but it is some what slow.
Looking the source code, I saw that internal Dictionaries and Collections are initialized without any initial capacity, while processing large json dataset that could improve de performance a lot.

Just add two static values in JsonReader class to initialize the capacity of the new Dictionaries and Lists;
It takes me 2.2 seconds (running on Psion EP10) to process a 200 kbytes json (minified) string.

Also, it is quite annoying that I can't inherent JsonWriter and overwrite the behaviour for datetime serialization.
I don't see any good reason to have sealed classes.
