Vue Resource should not be imported within Vuetable.vue

In my opinion, requiring the use of vue-resource should be up to the developer. I am already including vue-resource and as such, the error Cannot redefine property: $url gets thrown.

Please remove the import and force developers to pull it in themselves as a dependency.

Unless of course there is a specific reason for this. I would also like to see the ability to change out vue-resource for another similar package like axios.
