Improve the notification and pop-up system

This idea encompasses a number of changes to the notification and pop-up system. The main intent behind this idea is to reduce turn times and to improve QoL.

The specific suggestions to address that are as follows:
1. Instead of having notifications pop up, assign a different color to important notifications, or something of that caliber. Players could still via the current pop-up menu decide which notifications are to be marked or not. That way no immediate turn actions get prevented by invasive pop-ups, but the player will still notice them.

(As far as I know many people have turned off these pop-ups because they lead to missing fleets etc, kind of already defeating their purpose)

2. Disable animations in information windows (probe discoveries etc), or at least make them optional and turned-off by default. Though the snappy animations may only hide information for a second or two, there's a lot of them throughout a game. Especially in multiplayer this often leads to frantic clicking to skip past all animations, and without clicking animations away these seconds easily pile up and make a game take many minutes longer than it has to.

3. Implement more unique symbols. There's a lot of messages that can be conveyed through a single symbol such as the discovery of luxury resources. Right now neither the according symbol nor the tooltip shows which resource was discovered, forcing the player to open the big window for essentially a single word.

4. Condense info where possible into the side bar. Especially for event effects or curiosities this could save players a serious amount of time. Here's a mock-up which describes the idea better than words can:

This should be the gist of my suggested revamp. If this could become a thing I could of course bring forth more details, such as which symbols could be used to make small notifications better.
