[BUG] checkbox Old League Data functionality
Describe the bug The checkbox Old League Data does not do anything by itself other then making the selecting menu available, but when no seasons are selected it doesn't download anything. Best would be to download all seasons by checking the box, because this is a one time use function to get history data. And if people don't want all data, they can just refer to the method of selecting a single season.
I seperated this bug from #1413 for clarity purposes. @wsbrenk I am unsure if you already created a notification for yourself for this bug/feature?
To Reproduce Steps to reproduce the behavior:
- Download data
- Deselect "Download filter"
- Select "Old League Data"
- Do not select any seasons.
- In that case the checkbox doesn't do anything.

Platform information:
- OS: Windows 10
- Version 261
Additional context Possible solutions: Best: If the checkbox is checked without selecting any seasons, all seasons are included Alternative: If the checkbox is checked then automatically the first seasons is high-lighted as included to be included in the download (however I would strongly prefer that all seasons are included, because this feature is only used once normally)
Additional idea is if you download all seasons by only using the checkbox, that all "actual seasons" will be automatically downloaded, so that you don't have to click through the pop-up windows.
i put the previous series data download to the left check box tree. Now i'm looking for a nice indication of partial checked nodes (not all children are checked). I don't like the available TristateCheckbox that much.
