Add application loader before app start

Currently, the app tries to load instantaneously without any loading animations. The issue with that is, it is assuming that the user has a really good internet connection and PC configuration. In the real world, it is never true, there will always be a delay before any app can fully start. Especially with electron and JS, the paint time is expected around 2s before start. A loading animation will be a good option for the user to see before the application is in the ready state. This gives the app a polished look.

A good idea but this would have to be added on which is the main store page which the app uses which works too on your browser which does not need this loading animation
