decode nested Lists of ComplexType

[girishso]

Hacked to decode JSON arrays of ComplexType, because I needed it! :)

Example JSON

{
  "project":{
    "id": 1,
    "features": [{"name": "TDD", "details": {"tool": "rspec"}}]
  }
}

It creates multiple type alias if multiple array elements are present, unfortunately. Tried fixing it with no luck. Any hints appreciated!

Should fix #24

would this work in 0.19 #37 ?
@wscherphof made a really nice one but still has the complex types here
