Slate changes:
Allowed hyperlink decorator and hyperlink run to be more easily derived from by moving some functions/variables to protected.
Added new run & decorator for hyperlinks in tutorials that add an icon to the end of the run if required.
Only use icon-style run if in display mode (not in edit mode).

Improved text layout support when inserting runs/text or splitting lines on runs that were non-text (images or widgets). The text layout now inserts an extra text run when splitting a non-text run, which avoids issues where text was either being inserted into a non-text run (and vanishing), or an image run was being cloned (and appearing twice).
This also fixes the cursor movement in the multiline editable text when selecting over images or widgets (the cursor would jump to the start of the document as GetTextIndexAt hadn't been implemented. Additionally, it also fixes an issue where Measure was always trying to place the cursor at the end of an image run (ignoring the values of BeginIndex and EndIndex) which made the cursor offset draw in the wrong place.
These changes required the text layout to be able to create a default text run, which involved refactoring the text marshallers as the Slate text run now knows about the default text style, taking that responsibility away from the marshallers
Added tutorial-specific image decorator that accepts a content-relative or engine relative image path.
Added button to tutorial rich text editor to add new images.
All previously-imported images should still 'work'.

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.

Removed ability to independently set font size & colour etc. and replaced with a set of font styles we can use (and style appropriately). Added legacy code to deal with old-style text as best it can.

This solves a wrapping issue where STextBlock would incorrectly consume new-line characters when wrapping, as well as allowing it to use custom wrapping behavior (eg, CamelCase wrapping for asset names in the content browser).
This change also implements FString -> FText passthrough for SLATE_TEXT_ATTRIBUTE (it was previously performing FText -> FString passthrough, however this didn't fit well with the fact that FText has a more efficient method of comparing whether a bound text attribute has changed (see FTextSnapshot), so can quickly work out that the FTextLayout doesn't need updating).
This change adds FTextBlockLayout to handle the text layout cache for text block types (STextBlock and SRichTextBlock) and serves a dual purpose of moving the duplicated caching logic into a single place, as well as hiding it from the widget (so allowing the cache to mutate, even when called from immutable widget functions).
This change also increases the unification between the STextBlock and SRichTextBlock construction parameters, by allowing STextBlock to specify a Justification, Margin, and LineHeightPercentage, and allowing SRichTextBlock to specify its HighlightText as an attribute.

Icon is only visible if content is available for the editor in question.
Split editor settings into two groups - one is persistent settings and one is progress/state.
Tutorials record their dismissed state, so users can permenantly disable the 'nag' for a particular tutorial.
Tutorial content now solidifies when the mouse is hovered over it, so it can be made easier to read.
Fixed crash on startup if an intro tutorial was displaying rich text.
Also fixed crash for TTP# 345094, where a zero-length tutorial was being accessed.

The AppFramework module is intended to be used for compound widgets and UI related classes that are too specific (not basic enough) for Slate, but also not Editor specific (reusable in non-Editor applications and games). The test suite has been moved in its entirety for now, but core widget specific test classes will eventually be split off and moved back into Slate, so that they can live alongside of their corresponding widgets.
Other changes:
- moved to "include what you use" scheme for SColorPicker
- broke out color picker related widgets that may be reusable
- added forward declarations to reduce header include dependencies
