Fix memory leak of server browser entry UI elements

Browse source 
New UI elements were being created for every server info after refreshing the server list. At the same time, old UI elements were not being deleted when the server info objects are deleted. The use of `mutable` for this purpose was also rather unclean.

Now, a separate `std::vector` of UI elements is kept for all server browser entries, instead of associating the UI elements directly with the server info.
