Settings option to restore default value for that specific option / just an option in general

[Crystalwarrior]

Is your feature request related to a problem? Please describe.
It's really easy to scroll through the settings screen, modifying any values by accident, then having no clue how to restore defaults.

Describe the solution you'd like
Give every option a button to restore it to default, and a "restore to defaults" button

Describe alternatives you've considered
just have a "restore to defaults" button available, because right now you have to manually go to your base/ folder and delete your config.ini file - which is scary to a lot of users cuz they fear they'll break something.
