Genetics Rebalance: Negative mutations add stability, standarized ins…

…tability cost for mutations (tgstation#83439)

## About The Pull Request

PR has been reworked a bunch! Changes in bold. Some of the **HATE** is
now outdated.

**Negative mutations now allow you to have more positive mutations, via
reducing your instability!**

**All mutations have been overall standardized via defines on their
instability values. Many mediocre positive mutations have had their cost
reduced significantly!**

/// Negatives that present an uncommon or weak, consistent hindrance to gameplay (cough, paranoia)

Added a new height mutation: Acromegaly! It's the opposite of Dwarfism
and makes you uncannily tall. It also makes you hit your head 8% or 4%
(with synch) of the time you pass through airlocks. Wear a helmet!

**Injectors and activators' duration is now dependent on the
in/stability (absolute value) of the mutations to be injected! With a
minimum of 5-10-15 seconds for each type of injector. Also changed up a
bit how part upgrade cooldowns work, by making each tier reduce
cooldowns by 25-15-10% for each injector type.**

## Why It's Good For The Game


**> Negative mutations now allow you to have more positive mutations,
via reducing your instability!**

Genetics has been long in dire need of a rework. This isn't really one,
but it IS intended to increase genetics depth a bit and stave off its
stagnation, making it slightly more interesting than 'free shit', by
making it so **you can now gain more positive mutations, but you need to
figure out what you're going to take as a downgrade in turn.**

Genetic powers are heavily themed around comic book superheroes, and you
know what those had a lot? Debilitating drawbacks to their powers. Let's
replicate that.

**I intend to make a sister PR for this that adds more interesting
positive mutations (for the first time in decades) to genetics, so
there's an actual element of pick-and-choose involved**

> Added a new height mutation: Acromegaly! It's the opposite of Dwarfism
and makes you uncannily tall. It also makes you hit your head 8% or 4%
(with synch) of the time you pass through airlocks. Wear a helmet!

We have Super Tall. Let's add it to the game somewhere! With a fun
downside, of course.

**Gigantism is now a recipe mutation, mix Acromegaly with Strength to
get it.**

> **Injectors and activators' duration is now dependent on the
in/stability (absolute value) of the mutations to be injected! With a
minimum of 5-10-15 seconds for each type of injector. Also changed up a
bit how part upgrade cooldowns work, by making each tier reduce
cooldowns by 25-15-10% for each injector type.**

**Made no sense that a Glowy injector cost the same as a Hulk injector.
Just annoying. The cooldown is based on the absolute value, so a -30
instability injector would take ~30 seconds. This mostly so that
geneticists can't make a million modded syringe gun supersyringes**
