Allow using seeded noise for particle velocity and spawn position offset

[BMagnu]

Exposes the noise framework FSO uses for volumetrics to the particle system.
This allows particles to behave in noised-but-not-frame-independent-random ways.

As with volumetrics, it uses the DSL of the noise library to parse noise definitions.
While very flexible, this is also quite cumbersome and hard to visualize. I intend to eventually build a small utility program that can quickly visualize these noise patterns.

As an example, the following is a table that uses the new noise:

#Particle Effects
$Effect: NoiseTest
+Filename: AVMuzzle
+Radius: 1
+Lifetime: 8
+Duration: 20
+Spawns per second: 10
+Particle Count Per Spawn: 1
+Velocity Noise: color(scale(valueBasis(3,0),6), scale(valueBasis(3,1),6),0, 0)
+Velocity Noise Scale: 10
+Velocity Inherit: 0.9
