Party members order

**Warning:** Do not merge this pull request until fixes are done:

* Fix design "sort by" select in header menu:

    ![menu](https://f.cloud.github.com/assets/260983/1607988/9c2783c6-54bd-11e3-8ec2-d1642cb96434.png)

    Maybe replace text by icons ?

* Add a new **headerService** that will allow the divs **ng-repeat="profile in partyMinusSelf"** to reupdate themselves when the select option is selected.

I spent several hours trying to figure out how to autoupdate the header, but my AngularJS knowledge is too weak, and I can't dive more into it. Please have a guru take care of it :) ( @lefnire ?)
I'm no good with css and design either, hopefully someone can do this properly ( @zakkain ?)
