fixed isArrayLike returning true for 0

[melnikov-s]

before:

_.size(0) //undefined
_.size(1) //0

after:

_.size(0) //0
_.size(1) //0

There are probably other methods that are broken for the value 0 but _.size is how I discovered the bug.

The only other affected method is _.shuffle:

_.shuffle(0) == [undefined];
_.shuffle(1) == [];

Do you mind adding a test for _.size(1) and the two shuffles as well?

[megawac]

This test is sufficient and a good catch. Thanks @smelnikov!

Also found _.sample is affected:

_.sample(0, 1) == [undefined];
_.sample(1, 1) == []

@jashkenas: Mind cutting a 1.8.3 bugfix release?

[jashkenas]

Sure — but let's wait for a medium period of time before doing it. (Like, end of the week?) I'd imagine there are a number of minor things that can go in...
