Description

When a spectator is focused on a bot that they can take over, display a hint letting them know that they can take over a bot with the use key.

The latter part of this video shows a persistent client-side option to change the length of the hint lifetime, such that the hint could be disabled if a player already understands how the feature works and doesn't want that UI element showing up. (For example, they want to record gameplay without that hint showing up.)

Also upon starting the game I get hit with assert hud.cpp (444) : Assertion Failed: false

If a user has a keybind for +use, this is what it looks like so far:

wait, why is this using neoui

Admittedly, in the beginning I wanted to try learning how to use the neoui framework. On the other hand, maybe it would be much easier to override the player name text in the existing spectator hud, to write something underneath?

I'll give a try at the existing refactor suggestions, but if I hit a roadblock, I might consider looking at the spectator hud.

Pardon the squash, but I realized in the middle of making changes that there was a conflict when rebasing.

There was some discussion on Discord regarding which style of hint should show, so I added a config option to choose either a new minimal style, a refactor of the current central style we have been reviewing, and not showing the hint at all:

(And the other two option settings:)

This is what a "Central" config looks like:

And this is what the "Minimal" hint looks like:

Generally I think this PR is more complicated than it needs to be, I would only add the hint element and make it more general to support different hints like press use to pick up weapon or interact with buttons in the future, with a single option to disable hints.

[sunzenshen]

Took a shot at making the hud element a bit more general with the spectator bot takeover as the first use case.

Still feel like it should use the neuropol font but i might extend upon this in the future and we could look at it then
