Add new default games alphabetically

[Kebap]

Brief summary of issue / Description of requested feature:

• Status quo is unclear on where to add new default games to the list in connection window
• In fact new games got added in random positions, where in the past they were added at the end

Steps to reproduce the issue / Reasons for adding feature:

1. Games are to be added in alphabetical order per https://github.com/Mudlet/Mudlet/blame/bcb8673153bcf7535950254f3a0060f8112dd09b/src/TGameDetails.h#L65
2. Only doubt now: How to insert new games alphabetically into a non-ordered list?
3. I guess we may need to sort them all eventually
4. Part of this was already expected when decided on patreon in 2021-09
5. Discussion involved ideas on how to mitigate the pain of moving existing games
6. UI features (with minimal screen estate required) were suggested including:

• mark games as favorites, to be sorted at top
• sort games by usage, store how often they connect
• highlight 2-3 random games at the top, so not only games with A are shown

7. UI features were postponed at the time, just decided new games should be added alphabetically into the existing list
8. Eventually a new UI for connection dialog should be established alike Steam showcasing games in a more modern way

Error output / Expected result of feature

• Easy as a player to find games alphabetically
• Easy as a player to know where new games arrive
• Easy as a developer to know where to add new games

Extra information, such as the Mudlet version, operating system and ideas for how to solve / implement:

This assumes (but not sure) if 3k etc. are alphabetically sorted in front of A, or rather at T for THREE.

Let's assign numbers to show how the alphabetical sorting should be following this logic:

Whereas currently we have the games sorted in this order:

For comparison, this was the list of games at the time of decision (2021-09):

Grey areas show, where games got added into the list since then.

Summary:
Games got added practically everywhere, where a somehow adjacent letter was found.
Whereas before 2021-09 you could expect new games at the end in order of last added.
