- Exhumed: Restore more accurate pitch adjustment for Ramses.

* Use `maphoriz(-11)` instead of some voodoo degree amount so it's clear when comparing sources.
* Don't stop interpolating while doing Ramses.
* Apply Ramses pitch amount to `nVertDestPan`, just like the original.
* Don't reset all angles when initialising Ramses, just set the yaw angle.
* Don't return player's view to center when doing Ramses, use the delta between `nDestVertPan` and the player's pitch, using same formula as original.
* Comment in how normal/non-ramses `nDestVertPan` setting should be 8x the sprite Z move delta, not 2x. I know it's not correct, but its been this way for a long time and we probably should CVAR it.
* When doing the player's death pitch, it's 40.156 degrees (horizon of 108), not 38 degrees (horizon of 100). This was a misread of mine way back when.
