Servers sort by recently-clicked

simple.

if you click a server, It goes to the top and the top one pushed back to below the new one. eventually, the servers you don't click will go to the bottom.

I am not sure how it will work with folder ones... I have some ideas for folder ones

1. clicked one goes to the top inside its folder

2. the folder of the clicked one goes to the top of the server list. (so other servers will go together to the top)

3. folder system is disabled with this sort option.
