Felinid Soft Thieving + Trait (#500)

# Description

<!--
Explain this PR in as much detail as applicable

Some example prompts to consider:
How might this affect the game? The codebase?
What might be some alternatives to this?
How/Who does this benefit/hurt [the game/codebase]?
-->

Reworks felinid thieving to no longer act like passive thieving gloves
which grant invisible stripping (hereon referred to as hard stealing),
in favour of soft thievery (hereon referred to as soft stealing).

Soft thievery comprises of the following:
- A smaller popup, with the thief anonymised.
- A visible doafter bar
- A 33% faster strip speed, that stacks with Thieving gloves
- An additional ability to identify hidden items to better plan your
course of action

You no longer need to completely avoid felinids to maintain your
precious items as long as you pay attention. For a felinid to utilise
their thieving passive, they are encouraged to exploit any distractions
to make moves on a target. If there is none, create one through
conversation or other forms of player interaction. If you are suspected,
persuade your victim that the thief is in fact, the other person.

A faster strip speed makes thief bonuses diegetic to other players, and
also improves the value proposition of thieving gloves on someone who
already has thieving bonuses.

Any other race can also gain soft thievery via a moderate costing trait.
Non-felinid thieves are encouraged to exploit any felinids as a
scapegoat.

# TODO

<!--
A list of everything you have to do before this PR is "complete"
You probably won't have to complete everything before merging but it's
good to leave future references
-->
Code
- [X] IgnoreStripHidden - allows thieves to look into peoples pockets
- [X] StripTimeMultiplier - stripping at a multiplicative rate helps
strip bags/belts which creates trait value
- [X] Stealthy > Stealth - rather than a bool, distinguishes stealth
levels as an enum

Balance
- [X] Soft thieves can identify items in pockets, which creates player
agency
- [X] Soft thieves steal 33% faster, which stacks with thieving gloves
- [X] Victims to soft stealing get a smaller popup, useful if they're
preoccupied
- [X] Soft thievery is a trait, which Felinids get for free
- [X] Felinids no longer hard steal items

:cl:
- add: Added the Thievery trait, which provides various soft stripping
bonuses
- tweak: Felinids no longer have passive thieving gloves, they instead
get the Thievery trait by default
