UnrealEngineUWP/Engine/Source/Editor/IntroTutorials/Private/STutorialEditableText.cpp
Thomas Sarkanen fa824aad40 Added more hyperlink types for tutorials 
Added asset, code, tutorial and UDN hyperlinks. Tweaked UI to use combo box instead of the large amount of radio buttons it was using before.
Made sure importer & content use correct text styles.
Defaulted to rich text for content.
