Add maybeToList and maybeToArray transformations

[evilsoft]

Just two handy Transformers...well Transformations...

When working through a couple example of how to filter and transform without using reduce on Arrays and Lists, I found that a lot of value could be adding with some maybeToX transformations. The basically will take a Maybe to either a List or an Array. A Just instance will return a single element structure, containing the value in the original Just. While a Nothing returns an empty structure.

When used with chain this can be used to filter and transform a structures values in one go, without having to set up a mapReduce with alt to get the same result.

In addition to adding these functions and their documentation, Also added a couple links to the Result NTs and cleaned up some specs that suffered from :policeman:-y :spaghetti: artifacts.
