Weapon Reflection Movement Mechanic (#27219)

* Weapon Reflection Movement Mechanic

Adds a movement mechanic to deflection.
Standing still gives you your best chance of deflecting a shot.
Moving lowers this to 2/3rds. Sprinting to 1/3rd.

This allows for robust players to express better and provides
counterplay to someone finding a goober-strong deflection
weapon, giving more design space.

As part of this PR I've also touched the numbers of a few swords,
shields, etc. and modified some descriptions to make them read
better. The balance numbers are not remotely final, but as intent:

1. All the sidearm swords (katana, cutlass, captain's sabre) have the same damage. There's no good reason the "ceremonial" blade the captain has doing more damage than a katana.
2. The Captain's Sabre has a 30% reflect chance, dropping to 20% when moving and 10% when sprinting. This one is controversial due to the recent nerf, I suspect: This could easily be 15->10->5?
3. The Energy Katana has a flat 30% reflect chance.
4. The meme Throngler has a 30% reflect chance, dropping to 20% when moving and 10% when sprinting.
5. The E-Sword has a 30% reflect chance, dropping to 20% when moving and 10% when sprinting.
6. The Double E-Sword has a mighty 75% reflect chance, dropping to 50% and then 25%.
7. Both reflective shields - Mirror and Energy - have a 95% deflect chance, dropping to 63% then 31%.
