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?
(cherry picked from commit 162068640b)
Adds a tooltip parameter to `TreeItem::add_button()` and set a few tooltips in the Project settings and SceneTree dock.
(cherry picked from commit 29999942a2)
The other subfolders of tools/ had already been moved to either
editor/, misc/ or thirdparty/, so the hiding the editor code that
deep was no longer meaningful.
