Robert Müller 0b57d56f48 Overhaul server browser filter, details and friends tabs 
Move the "Filter", "Info" and "Friends" tabs to the top, above the tab content. Use icons instead of text for the tabs. Use animator to animate the tabs on mouse-over. Closes #6613.

Make spacings, corners and font sizes used in the filter, details and friends tabs more consistent.

Remove some unnecessary dark UI rect backgrounds.

Improve alignment of the number of friends with the heart icon for entries in the server list.

Improve layout of countries and types filters. Make the filters scrollable when there are many entries.

Refactor most of the server browser in preparation for replacing the DDNet and KoG tabs with a community filter, which will work like the countries and types filters. Split rendering of different server browser sections into multiple functions to improve readability. Reduce duplicate code for the countries and types filters.
