[Cuis] A few proposed is: additions

[Juan Vuletich]

Hi Phil,

At first, when I coded the #is: methods I thought about using them 
everywhere. But when the sender is really concerned about performance, 
#is: might be too slow. The old #isXX with a hardcoded answer is faster. 
You can check a bit the senders for #isBoolean, #isString, #isCharacter, 
etc. So, I don't have anything about implementing it in the classes you 
say, but please add a comment in the implementation in Object and in 
those subclasses where the older #isXX is still there, to explain the 
reason for having both.

BTW, several times somebody asked some good question like this one, that 
I knew the answer, but hadn't thought about a clarifying comment. This 
is the moment to add it!

Cheers,
Juan Vuletich
