Tweak environment in the Advanced Import Settings dialog

Browse Source 
Use a gradient sky to improve visibility in shaded areas,
while also helping the user orient themselves. The bottom of the sky
is black, while the top of the sky is white.

This change also makes it so that the Default Clear Color project setting
no longer affects the Advanced Import Settings dialog.
