Configurable sensor size:

- Added support of variable size sensor width and height.
- Added presets for most common cameras, also new presets can be defined by user.
- Added option to control which dimension (vertical or horizontal) of sensor
  size defines FOV. Old behavior of automatic FOV calculation is also kept.
- Renderer, viewport, game engine and collada importer/exporter should
  deal fine with this changes. Other exporters would be updated soon.
