[1.3.0] stoi error parsing playlist

[JasonMarechal25]

In GeneralDataReader.h:GetKeyValFromLine
We parse the section "[playlist]" of generalData.ini

If most values are in the form of "key += Number" one valid entry is "playlist_reset = False"
We use "std::stoi" to convert numbers, however "False" is not a valid representation of a number.

Historically we used std::atoi which does not throw and return 0 in case of error.

std::atoi is useful for playlist_reset entry, but if we have an invalid "key += Number" entry it will silently fail and wrongly set 0 as value for the key.

I think we should handle the exception properly in case Number is invalid and generate meaningful error.
We could however ignore "playlist_reset" line entirely either inside GetKeyValFromLine and return {"", 0} or not call GetKeyValFromLine for playlist_reset line.

Fix should be applied to 1.3.0 release. Check 1.2.x version if bug is present too.
