Colorize history events based on type

[BartXZX]

Is your feature request related to a problem? Please describe. While browsing/scanning/fast-scrolling through the history events (without filtering on event type) its relatively hard to see what type a history event is. (Child workflow/activity/signal).

Describe the solution you'd like Colorize it! Just like on the workflow list where the statuses are colorized, making it super easy to quickly identify what I am interested in.

Describe alternatives you've considered The filtering works very nicely, but sometimes I want the entire context of the history, and still be able to discern event types at a glance.

Additional context None

@canvanooo Just let us know what you want to do here. We can role this into the “Better Event History Visualization” line of work. /cc @rylandg
