>+        [Settings] Add initial support for generating preferences related code
>+        https://bugs.webkit.org/show_bug.cgi?id=178656
>+
>+        Reviewed by NOBODY (OOPS!).
>+
>+        As a first step towards getting off the macros in WebPreferencesDefinitions.h
>+        and reducing the overhead of adding a preference, this change generates adds
>+        WebPreferences.yaml where preference changes will go, and generates much of
>+        WebPreferencesDefinitions.h from it (all the custom defaults moved to 
>+        WebPreferencesDefinitionsBase.h). Subsequent changes will remove the need for 
>+        the macros in WebPreferencesDefinitions.h entirely.
>+
>+        * CMakeLists.txt:
>+        * DerivedSources.make:
>+        * WebKit.xcodeproj/project.pbxproj:
>+        
>+            Add new files / rules to generate WebPreferencesDefinitions.h.
>+        
>+        * Scripts/GeneratePreferences.rb: Added.
>+        * Scripts/PreferencesTemplates: Added.
>+        * Scripts/PreferencesTemplates/WebPreferencesDefinitions.h.erb: Added.
>+        
>+            Add scripts and template to generate WebPreferencesDefinitions.h from
>+            WebPreferences.yaml.
>+
>+        * Shared/WebPreferences.yaml: Added.
>+        
>+            Configuration file for preferences.
>+        
>+        * Shared/WebPreferencesDefinitions.h: Removed.
>+        * Shared/WebPreferencesDefinitionsBase.h: Copied from Source/WebKit/Shared/WebPreferencesDefinitions.h.
>+        
>+            Moved custom defaults to new WebPreferencesDefinitionsBase.h. Removed the need for 
>+            FOR_EACH_WEBKIT_STRING_PREFERENCE by using custom defaults for the font family values.
