Title: Override implementations of -map: and -filter: in RACArraySequence.

I used to have `RACStream` implementations for `NSArray`, but since `RACStream` is a class and not a protocol now, I switched my code to convert to and from `RACSequence` instead.

Unfortunately the size of the arrays causes the deallocation of the lazy sequences to overflow the stack.
I implemented these methods overrides to solve that.
