* Tweak after placement in world and local space using standard level editor gizmos.
* Removed Single place tool settings. Since we're using the TRS gizmos, these settings are unnecessary.
* Moved cycle through palette to shift + right click to match other viewport functions (i.e. cycling static mesh previews).
* Placement mode now inherits from default ed mode, so we will get the new gizmos as they come online.
* Fixed a bug in the select tool where the input was never making it back to the viewport for handling.
* Fixed a bug in the ITF Editor hooks where the mouse capture was incorrectly reporting and eating the input from the viewport.

- fix broken sculpt material that went to white in many cases, replace with diffuse shading and rim light in Emissive channel / unlit texture
- add image-based sculpt materials provided by techart, expose custom variant that allows user-defined shader image
- make flat shading optional in view settings, for relevant shaders
- reorganize properties and update tooltips to be more informative
- fix broken Falloff support and expose in property set, display in brush highlight. Make this separately exposable in BaseBrush property set since we don't need Strength.
- add viewpoint-based Sculpt and Plane brush modes
- fix brush preview location when in hover, was not respecting target surface setting
