feat(uiSref): add support for transition options

[roryf]

Allows optionally spcifying options to be passed to $state.go:

<a ui-sref="contacts.detail({id: contact.id}, {reload: true})">

will translate to

$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?

<a ui-sref="contacts.detail({id: contact.id})" ui-sref-options="{reload: true}">

Just realised this is basically the same as #644 and #628. Failed at the first hurdle: check existing issues...

[roryf]

and #694.

Yeah, we're gonna go with the other implementation with the separate attribute. Thanks though!
