KSPedia Scene lacks code to implement

[schpoorky]

In source file 'Enums.cs', "public enum Scenes" line 25 lists KSPedia. However, in 'EventManager.cs' lines 534 to 536 have only commented-out stubs of code to detect entering and exiting KSPedia in-game.

This may have been left out because the KSPedia can be spawned in two different scenes -- the "SpaceCentre" as Brit Pizza has internally respelled it from the game's own proud and righteous American spelling, and in the Editor scene (VAB and SPH). The other GUI-only pseudo-scenes like Mission Control and Research & Development despawn to the SpaceCenter (!) scene, but one cannot simply take the same approach with the KSPedia.

Also, it's kind of an oddball scenario to target, having different music start up when you look up reference material, only to return to regularly scheduled VAB music or nature sounds.

Simple fix is commenting out KSPedia code.
