feat(dynamic): Support dynamic flag on a state declaration

This feature supports a `dynamic` flag directly on the state object.
Instead of creating individual param config objects, each having `dynamic: true`,
you can specify `dynamic: true` on the state.
All of the state's parameters will be dynamic by default (unless explicitly overridden in the params config block).

```
var state = {
  name: 'search',
  dynamic: true,
  url: '/search/:query?sort'
}
```
