Displaying the current active server in home-page

I couldn't find good place to display current active-server in TextView, so I implemented that in another way
Fixed #161

description	Image
Added color attribute
Suggests random four colour every time from redableColors file
Now added servers can be identified with specific colour
The final!

• it's not the best but really will help to identify active server with specific color(solid-circle) on profile-navigation button, if longPressed it will toast the current server as in the last image showing
• Please don't consider the color variation in given images, screenshots are taken at different times while testing
