Add more Server Customizations and Improvements

1) Possibility to add an image/gif in the title or background of channels and categories

(maybe just use animated emoji or own emoji in the titles are good) 

2) Give roles in mass without a bot (once I changed manually like 100+ user's roles just because i didn't know wich bot use)

3) View members like a map in the server settings and not just searching them per role

4) Could choose the priority between role's permissions and channel's permissions like a switch for each category/channel
