Add a loader untill the firebase data is loaded

[Abhishek-kumar09]

If you are logged in and see the profile page, the data is loaded after sometime from firebase but the page is rendered without any content. Need to add a loader or some beautiful loader that will be displayed untill the data is fully loaded from firebase
