Add notifications #16
Description
This app could really use a simple way to show notifications in the corner of the screen. These could be used:
- To replace all instances of ErrorComponent;
- When using a "copy to clipboard" button;
- When logging in or out;
- When creating a match;
- Or basically anytime that user modifies backend or frontend data.
They should also appear automatically whenever an error is raised.
Basically, like the Insalan website or the Langate.
