EmuDeck 2.3.10 Unstable & more stuff

New releases for the unstable branch ( might contain bugs! ) and some more stuff.

1 - SteamOS & Windows

• Added new "Level of integration" selection page for Custom Mode so you can select how to use EmuDeck: By using EmulationStationDE, RetroLibrary ( SteamOS only ) or SRM. Should I add this page to Easy mode too? I need feedback on this :)

• ESDE & Pegasus autoadd to Steam, when installing any of these frontends they will be added automatically to your Steam Library, no SRM needed!

• Fixes logs not loading on Windows

2 - New Easy mode defaults:

- Windows will install ESDE by default, as it's the easiest way to play games on Windows
- SteamOS will install RetroLibrary by default, as the idea is to use this for novice users

ESDE, Pegasus and SRM will still be able to be installed using Custom mode or by using Manage Emulators to manually install them.

3 - RetroLibrary 1.5.0

RetroLibrary was created by the sole purpose of having the easiest way for newbie users to play games, without messing around with parsers, scraping artwork and metadata, etc. that's why I'm focusing on making it the default option for Easy Mode and optional on Custom Mode, but like I said... I'm open to feedback!

- I've pushed a new update with the final two themes: Steam and Retro, you can see how they look in the video above. Still needs some visual adjustments for resolutions other than the SteamDeck and is missing launching PS4 games. I'm still working on a Windows port
- Fixes PS3 artwork not showing
- Animations have been added and refined so the experience is more smooth
- Remembers last category and last game played when coming back from playing

4 - A new member comes to the team!
Please welcome David as a new member of EmuDeck, he'll be helping me specially with testing in what I believe has been the weakest side of EmuDeck so far, another set of eyes will help to have more stability and less bugs
