Added entities emitting sounds on damage and on death

Added textboxs to server settings to control played sound

Fixed class entry textbox not showing when particle textbox was included

Added particle effects playing on damage in addition to in-engine effects. Any particle effects already available on the server can be selected by way of textbox.

Particle effects get removed automatically after a controllable time in case the effect used doesnt 'die' naturally

Added slider to control the time before a particle effect is removed

-Added changing the on death and on damage FX to be server/admin defined, defaulting to the in-engine FX originally used

-Added on damage effect scaling with damage dealt, as a multiplier to the magnitude. Some in-engine FX can't be scaled so if scale doesnt change thats why.

-Added checkbox to enable/disable scaling the damage effect by damage

Hotfix to prevent negative health/weight or health/volume ratios giving entities negative health. Health has a minimum of 1. The editor tool should intentionally override that limit.

Sneaky hotfix to handle the damage rule setting being nil on newly spawned entities causing them to always take damage

Rewrote code to have minimal use of networked variables due to computational expense

hotfix for mod conflict

Reworked some convar behaviour to be more intuitive

Added a control to settings to enable/disable damage to parented props

Hopefully fixed nonadmin clients being able to remove or add rows to the entity filter clientside which makes their filter list not match the actual list in use by the server
