Improved supports for in-app/game notifications and toasts

[BenCheung0422]

This feature is reserved for future use. This adds a support for in-app notifications, where toasts in the screen. It is different from in-game notifications, bare text only, as this includes a frame, and the color can be changed. This is important when there are some alerts, warnings and important information needed to notify the users.

I have several ideas about box popups and notifications: (fading is not supported right now)

• App status bar with icons (fade inappear fade outdisappear) - quick inspections about status (top bar near top-right)
• Toast notifications (slide in slide out) - quick informative notification (near top-right/bottom-right corner sliding on side)
• Bottom slide popup (slide in slide out) - app tool bar? But currently there is no such possible uses. (near bottom-right corner sliding on bottom)

Position for toasts may be configurable to upper or lower positions (also for each type of toast notification?).

Additionally, achievement unlocking toast is added to replace the text-only notifications regarding unlocking achievements. (https://discord.com/channels/280723930942013440/1141498209634623539) This improves visual quality of life.

In-app notifications are usually a result of bad game design. Using this will make the game feel more like a cheap mobile game than an free and open-source sandbox game. Perhaps an icon can be showed insted when a controller is plugged in?

App status top bar (shows automatically for 2 seconds on startup and shown when "9" (I was seeking to use symbols but it seems like they are not supported, which is not rightActually it is possible, but with different wordings) is down)
