FenodyreeAvandGitHub be17521156 Fixes armour checks, rubbers checking siemens and pain interrupting t… (#23023) 
**_- bugfix: "Fixes all rubber bullets dealing damage twice."_**
Rubber bullets were dealing their pain damage twice, while checking if
they should shake your screen or not.

_**- bugfix: "Fixes all attacks that dealt pain damage checking siemens
coefficient. This makes everything but hardsuits and voidsuits stronger
against rubber bullets. Insulated gloves are also no longer immune to
rubber bullets."**_

Hardsuits has siemens 0.1, meaning they took 10% damage from all stuns.
Now rubber bullets check their melee armor. Hardsuits are now weaker, or
the same against stuns.

Regular armor all has siemens 0.5, they took a flat 50% reduction.
Security armour is slightly weaker to rubbers, ablative and ballistic
are much weaker. Combat armour is roughly the same, or slightly better.
Riot armour is a lot better.

Voidsuits all had better siemens than armour, all voidsuits are now
weaker against stuns.

Finally, all jumpsuits had 0.75 siemens, but no (or nearly no) armor.
Combined with the fix of them hitting twice this means that rubber
bullets previously dealt 50% more damage against people in jumpsuits
than they do now.

**_- bugfix: "Fixes pain failing to make your blurt out whatever you
were typing. Now getting shot will cause you to say whatever was in the
typing window when you were hit and close the window immediately,
allowing you to move."_**

No more getting stuck in the typing window when you're getting sprayed
down by an STS!
 

_**- bugfix: "Fixes all attacks that had manually set armour checks,
previously they ignored the armour they were meant to check and decided
what armour affected them based only on their damage type."**_

Weapons that were set to specifically target armour types, such as
explosive projectiles (rockets, etc) were instead defaulting to the
damage type they dealt. So a rocket to the head was checking your melee
armour, not your bomb armour.
