[FIXED] Added new sound emitter based off the Qilers one
[ADDED] High-speed inputs to sound emitter (I have no idea how fast they really work, so assume they work the same speed as regular wire)
[ADDED] Pitch & volume sound emitter inputs (that actually work). Input value is 0..2 for pitch, 0..1 for volume. Default volume is 0.5.
[ADDED] LFO inputs to sound emitter (low frequency oscillation). LFO Types:
0 - None
1 - Square [doesn't work yet]
2 - Tri [doesn't work yet]
3 - Saw [doesn't work yet]
4 - Sine [doesn't work yet]
5 - Random noise
LFOModPitch/LFOModVolume - amplitude of LFO for pitch and volume
LFORate - LFO frequency in HZ (up to 100 Hz)
[ADDED] Sample input to sound emitter - for now it toggles between base wave samples (square, saw, tri, sine, in that order)
[ADDED] Basic wave samples
[FIXED] Default sound is now square wave @ 440HZ
[FIXED] Console screen lua spam when spawning missing model
[changed] cleaned up more stools' code
[fixed] some ents not keeping updated values when duplicated
[added] presets to some stools
[fixed] some ents not being added to cleanup when duplicated
[fixed] some ents not being staying frozen when duplicated
[fixed] some ents cleanup & undo text
[changed] moved many stools control panels over to DForm functions
[changed] made easier to add preset control to cp
[changed] made easier to add cleanup and undo lang to stools/bak
[changed] made easier to add
