Grav Shields & M/E Shields

I'm not a big fan of the sand/smoke/etc screen effects, for reasons that
have been expressed by others a few times. 

Two prototype Shield systems from Midbar skunkworks:

Gravitic Shields - Same function as normal screens, but works against
particle, torp, or mass (i.e. RG) weapons/missiles/torpedoes only. Ship
with
gravitic shields cannot fire particle weapons/missiles/torpedoes on
turns
the shields are active. Fighters treat shields as screens of same level.
Cost/mass/levels are  the same as screens. Missiles, SLMs, Torps,
receive -2
per die of damage per shield level (max level is 2). Energy weapons (or
other  weapons affected by screens)  are not affected by Gravitic
Shields.
Alternate effect (cinematic only): 
     Instead of restrictions on firing weapons, ship with active
Gravitic
Shields has thrust reduced  by 50%.

   Mass/Energy Shields (ME shield) - Trek type shield. System has
emitters
and  generators generator costs 5% ship mass/level. Emitters: 360 degree
coverage = 3 mass, 180 = 2 mass,  60 = 1 mass. Acts as screen against
beam
weapons. Reduces other damage by shield level.	If  a shield facing
receives
more damage than its level from a single source (weapon, not ship), the
emitter facing that direction makes a threshold check at current level.
