Updated the generation script to account for Python 3.12 deprecation of 'datetime.now()'.
Re-generated the MAME resource files from the following DATs:
* MAME 262 (Jan 2024)
* FBNeo (22 Feb 2024)
* Libretro Mame2003-Plus (22 Feb 2024)
Prevent game launchers in a directory used as game launcher, as FileData::addChild() is only valid on filesystem folders with no or no valid game extension for that platform.
Example:
```
scummvm/Violet.svm/ # directory acts as game launcher in ES, bc. of the extension.
├── Violet.svm # file is another valid game launcher.
└── Violet.zblorb
```
May be end up in the gamelist as:
```
...
<game>
<path>./Violet.svm</game> <!-- <game>-element bc. ES recognize only those as launchable -->
...
</game>
<game>
<path>./Violet.svm/Violet.svm</game> <!-- <game> can not be added to parent node as it is also a <game> and not a <folder> -->
...
</game>
```
1. folder elements are loaded when present in a gamelist and if they match the filesystem representation
2. missing optional folder elements are rendered empty in theme (and not "unknown")
3. As before non-existing folder elements are generated by ES, with mandatory elements <path/> and <name/>, but with this PR, whenever metadata is edited for this folder object (FileData class) it is persisted
4. Editiing metadata on existing <folder/> gets persisted too
5. UI metadata edit: layout fix that renders entered metadata not centered when returning from editing
6. UI metadata edit: format tooltip for date format in release date field
1. Menuitem text shortened to fit on 4:3 or 5:4 displays.
~~~2. <DEFAULT> renamed to "Favorites".~~~ undone
~~~3. Simplified applySettings() as I could not manage to defaultScreenSaverCollection->getSelected() to be not set.~~~ undone
4. setupScreenSaverEditingCollection() renamed to handleScreenSaverEditingCollection().
- Use constant var instead of -1 for setViewportTop()
- integrate logic to list cursor refresh into setCursor()
- Fix cornercase with cursor placement after screensaver 'A' btn press
- Fix cornercase in GuiGamelistOptions: If user stands inside Collections system which shows folders, then the option to launch a system only screensaver should not be available, only inside such folder. Additionally the Retropie Config 'System' should also not show the launch system screensaver menuentry.
- Add option to launch random video/image screensaver with games from only the current system
- Adjust screensaver controls to allow A to select the current game without launching
