Project Settings: Use capitalized properties.

There's been some inconsistency between the ProjectSettings and EditorSettings:
One would use "snake_case_properties", the other "Capitalized Properties".

This fixes that by also using capitalized properties for the project settings.
(It's actually the default, so the line setting it to false was just removed..)


Was there a strong reason for using snake_case here in the first place?
