Added basic functionality to server selection UI.

Basic selection and updating of the selected server has been added. There are a few subtle mechanics which need to be added still, such as keybind shortcuts (enter to submit, etc). In addition, functionality still needs to be added to generate the list of servers from the manifest file.

Fixed a minor issue with the login view.
Updated play button styles.
Updated dependencies.
