Lots of 3D improvements:

-Object Manipulator Gizmo keeps proper scale in all windows and projections, (configurable on settings too).
-Manipulator gizmos for other objects (camera, shapes, etc) massively improved and bug-fixed.
-Manipulator gizmos are different for edited object and other objects.
-Properly highlight manipulator gizmo handles when hovered.
-Fixed bugs in fragment program when using more than 1 light together.
-Reload png/jpg files automatically in editor if edited externally.
-Added 4-stages Parallel Split Shadow Mapping, to improve shadow quality in large scenarios
-Added PCF13 to improve smoothness of shadow borders
-General optimization of directional light shadow mapping for Orthogonal,PSM and PSSM.
-Fixed normal mapping when importing DAE files, works nicely now.
