feat(uiSref): add support for transition options

Allows optionally spcifying options to be passed to `$state.go`:
```html
<a ui-sref="contacts.detail({id: contact.id}, {reload: true})">
```
will translate to
```javascript
$state.go('contacts.detail', {id: contact.id}, {reload: true});
```

This does somewhat muddy the syntax between the `ui-sref` attribute and `$state.go`. Wondered whether a `ui-sref-options` attribute might be a better implementation?
```html
<a ui-sref="contacts.detail({id: contact.id})" ui-sref-options="{reload: true}">
```
