Rename HasValidProperty to HasValidPropertyNode to make the behavior match the name, and clean up some comments
Fix several details customizations that weren't correctly checking for property validity before derefencing GetProperty() or AccessRawData(). This fixes the original slate crash as well

[UETOOL-125] - Have the "return to defaults" arrow on a brush's texture actually go back to the size of the texture
#change Customization of property rows now supports passing reset to default customizations to child properties so that structs like vectors can have their components handled by the same custom handler as the parent. Properties identify themselves by passing their handle to the delegate.
#change Reset to default is now set on properties using FResetToDefaultOverride class containing the delegates and ovrride behaviors.
#change Slate brush customization sets custom reset behavior on the Image Size property and uses the texture size as the default size.

Added FPropertyHandleBase::NotifyFinishedChangingProperties to handle generic calls to NotifyFinishedChangingProperties.
Text Customization will now NotifyFinishedChangingProperties so the data can properly be captured.
