Loader Screen Added

[SamarpanCoder2002]

Description:

Added Loader Screen At Sign UP and LogIn..

Points :- Sometimes Loader Screen Can't see if the authentication process is very fast... It totally depends on server speed.... If Process fast, then loading screen stay for just miniseconds...So, you may not be notice it...

That's why I add this debugging statement picture, helps you to track the process..

I also Added Debugging Statement like true and false, if you have confusion if I implemented it or not

2. When you click to signup or login, You may notice a loader screen above the screen is circulating....

Hope this helps to finish your confusion...
