• Logging, JSON field name, refactoring from Request.Companion
• Clearing the users when reseting the Cache
• Image to test the avatar & PATCH/multipart testing

TODO: fix missing PATCH requests.

• Better documentation in Request & better platform-types handling
• Removed unneeded try-catch

How to hide the title bar of an Activity: https://stackoverflow.com/questions/2591036/how-to-hide-the-title-bar-for-an-activity-in-xml-with-existing-custom-theme

Instead of using a Queue, use a List that interacts as a Queue. It should be possible to add posts to the front of the list (eg. when clicking the notifications, the post that is selected gets to the top of the post queue)

In Kotlin, every exception is unchecked. The lib can stay as it is for end-users, but it automatically will not contain checked exception.

Note: after looking at the new designs, I noticed that the bottom navigation bar is gone altogether. I'm not going to remove it *now*, but I'm not going to improve it either...
