Create a new window for editing each light

[Nicolás Uriel Navall]

Describe the new feature or enhancement

Currently, we are using the native Unity Explorer window for editing each light, which is not ideal since it has a lot of parameters and information that we don't care about.

Ideally, pressing the button to edit the light would create a new window just with the properties we are interested in, like color or angle for spotlights.

Including controls over its positions and orientation could also be useful for being able to move the lights around while the camera is fixed in the composition we want, to see how these affect the scene in real-time.

For now applied filters to the inspector to focus on the light properties on a387207. We should still think about making our own custom solution tho.
