add a format 'len(Data): int' to count elements in a slice

[craftgear]

Add a new format to count elements in a response slice.

This would be useful when you expect an exact amount of data to retrieve.

Usage:

## Get /foo/total
Get 10 items
=== 
len(Data): 10

Great stuff.

Since we're using JavaScript notation, would it make sense to do Data.items.length?

That makes sense.

Then how about making it as Data.length? When you get response as an array response.length is intuitive IMHO, moreover it's shorter.

[craftgear]

Wait, length should work with properties and strings.

Let me think about this again.

[matryer]

Is this ready to go now?

[craftgear]

Not yet. Give me a little more time.

Maybe Data.length(): 6 would avoid the collision with a length attribute?

[matryer]

Maybe it’s not a collision… you might well want to assert the length of a string?

@matryer Yes, I try to check String.length. Do you think it's unnecessary?

[matryer]

I'd love to get this done and into the next pre-release if possible. @craftgear can you have a look at my comments please?
