Title: Multiple step collections

Augment Dullard so that it supports multiple sets of steps. Running `dullard` with the following `.dullfile`
```javascript
{
"steps" : {
"steps-a" : [
"one",
"two",
"three"
],

"steps-b" : [
"four",
"five"
],

"steps-c" : "six",

"default" : [
"steps-a",
"steps-b",
"steps-c"
]
}
}
```
would result in the steps executing in this order: `one`, `two`, `three`, `four`, `five`, `six`

It still of course supports just an array of steps.

```javascript
{
"steps" : [
"one",
"two",
"three"
"four",
"five"
"six"
]
}
```

This PR also sneaks in support for single task steps not wrapped in an array.

```javascript
{
"steps" : {
"fooga" : "wooga"
}
}
```
