new in this version [1.8.0]
-- HIGHLIGHTER --
CHANGE: now Highlighter does not require ColorTransition compoenent to work. If a ColorTransition component is present on the same object, the highlighting effect will be mixed to color transitions of ColorTransition componenent
ADD: static Highlight and DeHighlight method

-- EDITOR --
FIX: now in Highlighter editor mix mode is shown only if Mode is set to Color or ColorsAndOutline

-- OUTLINE --
CHANGE: in order to use outline features, it is no longer necessary to add "outline" layer to tags and layers of the project
CHANGE: brand new design for outline system to make it simpler to be used. It's now possible add, remove, enable and disable OutlineTarget compoenent (runtime and editor) to make OutlineTarget component work. It's however possible to control it through Highlighter component (recommended)
OPTIMIZATION: now post-processing involves only a portion of the screen (depending from objects in screen space)
