Change startup defaults

- Default Lamp increased strength (10x stronger)
- 3D View & Camera Lens = 50mm
- Camera film size = 36x24mm Full Frame
- Render Size Percentage = 100%
- Render Display = New Window
- Scene Units = Metric
- Color Management View = Filmic
- Workbench Object Overlap = ON
- Headers on top for all editors, except the Timeline at the bottom
- Default Properties tab = Object Properties
- Generate UV's = ON
