Modified server info to use docking functionality

The server info now functions in a way similar to docking elements. Elements can be stacked to either above or below the player list without leaving unnecessary white-space.

The password input was also revised. Additional padding was added and the label was replaced in favor of placeholder text (and more input width).

Docking example; this should be handy in the future if a 'Favorite' button is added
