Fix custom blocks with no fog in .cw files mistakenly still being loaded with fog density

Browse Source 
The easiest way to reproduce this was to use noclip to move inside a solid custom block, and then notice the horizon has become black fog

To solve this problem for both current and past client versions:
- when the read FogDensity value is 0, the in-memory fog density value is set to 0
- when writing FogDensity values to disc, 0xFF instead of 0 is written to indicate 'no fog' (since older client versions convert FogDensity values of 0xFF to 0 in-memory)
