Adds various controls for customising the Sonic Beam weapon effect.

[CCHyper]

Closes #540, Closes #547

This pull request adds various controls for customising the Sonic Beam weapon effect. It also implements a possible fix for the common "WaveClass" crashes see on older hardware (see issue #540).

Special thanks to @askhati and @MortonPL for assistance with the math calculations, and @tomsons26 with the drawing code.

SonicBeamColor=<r,g,b> Color of the sonic beam, in 24-bit RGB. This color entry is used to enable the new drawing system, so you may need to experiment with the options below to get the desired drawing effect.

SonicBeamIsClear=<boolean> Is the sonic beam clear (no color)? Defaults to false.

SonicBeamAlpha=<float> The alpha blending of the sonic beam. Defaults to 0.5.

SonicBeamSineDuration=<float> The duration of one wave effect pattern cycle. Defaults to 0.125.

SonicBeamSineAmplitude=<float> The amplitude of the sonic beam pattern effect. Defaults to 12.0.

SonicBeamOffset=<float> The amount to offset the pixel data under the sonic beam. Defaults to 0.49.

SonicBeamStartPinLeft=<x,y,z> Defaults to -30.0, -100.0, 0.0 SonicBeamStartPinRight=<x,y,z> Defaults to -30.0, 100.0, 0.0 SonicBeamEndPinLeft=<x,y,z> Defaults to 30.0, -100.0, 0.0 SonicBeamEndPinRight=<x,y,z> Defaults to 30.0, 100.0, 0.0 Start and end pins for the shape of the sonic beam.

SonicBeamSurfacePattern=<string> The pattern for the sonic beam effect. Available options are; circle, ellipse, rhombus, and square. Defaults to circle.

SonicBeamSinePattern=<string> The sine wave pattern for the sonic beam effect. Available options are; circle, square, sawtooth, and triangle. Defaults to circle.
