Unique Glove Fibers (#642)

# Description

Cherry-picked from Delta-V, originally by @WarMechanic
(DeltaV-Station/Delta-v#1455).

Original Description:

> Every pair of gloves now has its own fingerprint, so items can be
traced back to gloves which can then be traced back to people.
> 
> ## Why / Balance
> 
> Evidence is very important to court cases running smoothly, so
detectives now have more evidence that can certify whether or not John
Syndicate's behaviour is valid. Traitors are now encouraged to either
clean evidence off syndicate gear regardless of glove status, or use a
disposable pair of gloves specifically for handling syndicate gear to be
disposed of later.
> 
> Aside from being required to obfuscate evidence you leave behind,
there is now a value proposition to searching glove prints of
departments. Wearing gloves that does not correspond your department can
punish an unknowing detective into searching the wrong people.
> 
> ## Technical details
> 
> `FiberComponent.cs` now stores a Fiberprint variable like
`FingerprintComponent.cs`. The code for assigning a fiberprint is the
same as the fingerprint. When evidence is placed on an object, the
fiberprint is concatenated to its localised fiber type.
