Update to support custom initial page load

[gotolino]

I needed to use URL query to know in which page the user was. I put an initial page tag to know which page the user would like to open.

The tag would look like:

    <div class="col-sm-12 pagination-container">
        <dir-pagination-controls
            class="pagination"
            max-size="8"
            initial-page="4"
            direction-links="true"
            boundary-links="true"
            on-page-change="changePage(newPageNumber, meta.limit)">
        </dir-pagination-controls>
    </div>

Hi, thanks for the PR.

Could your use case not be satisfied by using the current-page attribute and setting it to, say, 4 when the controller is initially loaded?

Hi!

That was my initial approach. I injected the pagination service in my controller to manually set the current page using the setCurrentPage(). But I needed the paginationId, which I did not know how to get. Ended up using the default value '__default' to solve the problem.

Anyway, I thought using that approach was a little bit hacky, since I had to look through the code and hard-code the pagination id in my controller, and had to inject the paginationService just to set the current page this one time. So I took the liberty to change the directive so that the logic remained there, without the need of external influences.

Well, I thought it could help someone, so I made this PR. It took me some time to discover how to do that.

Hi guys,

Sorry about the long delay. I still don't understand why you needed to get so hacky with the paginationService stuff. What about this: http://plnkr.co/edit/Cycne8sw1lRlMqpc0rRS?p=preview

Here I am simple setting the $scope.currentPage var to 4 in the controller, and declaring the current-page attribute on the dir-pagination directive. Does this not fit your needs?
