[Minor] Hide some visual effects globally

[Coronia]

• It is possible to toggle shake screen effects (ShakeX/Ylo/hi) off by setting HideShakeEffects=true.
• Phobos's Laser Trail effects can also be toggled off.
  • If a LaserTrailType has CanBeHidden=false, it can't be toggled off by setting HideLaserTrailEffects=true.

In artmd.ini:

[SOMETRAIL]                  ; LaserTrailType name
CanBeHidden=true             ; boolean

In RA2MD.INI:

[Phobos]
HideLaserTrailEffects=false  ; boolean
HideShakeEffects=false       ; boolean

compared with previous PR, this is done with the consideration that it can be toggled in game. Hence, it'll only work on the drawing process of laser trails while not interfering others
