Network optimisations by Redox!

"Stop using net.WriteTable, improve net efficiency"

Tweaks

Smaller batch size, 200 > 50
Properly cleanup the serverside syncing timer and tables
Make syncing wait 1s after a save load

Client error stomp.

Step sounds now match the advanced material of props.

By default, the step sound system checks the actual texture for a sound, then checks the noise texture for a sound.
Can also manually override stepsounds.

Can be enabled/disabled by serverside & client convars.

+ Rework bumpmap system, so it actually works

Fix preview not displaying sometimes
reworked internal preview material changing

Added "Preset" support.
"Alphatype" setting is now properly previewed.
Can now rotate noise textures independently.
Fixed some bugs that made noise textures hard to copy.
