Changing default parameters

[Stephan Koppel]

1) Make equirectangular set and Y filp to be default. While adding environment map we always need to check same combination - set it to equirectangular, check Y flip. It will be nice if these are checked for us by default.

2) Uncheck "camera lamp" in scene editor. Everytime when we uncheck it in scene editor after reopening SSE this lamp is casting from camera...pretty annoying little thing, so it will be nice to have it unchecked by default.

3) Ctrl-scroll is too fast by default. If we need to change some parameters we can use pressed ctrl and wheel over the parameter, but it changes too fast. It should be twice slower, or you can add ctrl+shift to activate "slow parametres scrolling"

Implemented in the version 0.9.1 About your last offer, I have chosen the option of half scrolling using ctrl+shift
