Consider using same control for pickup + use weapon and have dedicated drop key

Description

Right now we have a "Shoot" control that uses weapon, and a "Grab / Drop" which picks up or drops a weapon.

Some feedback from playtest:

It's not clear to me why "Shoot" and "Grab" are different controls. My intuition is to always use shoot to pick up melee weapons / crates and it's very distracting to force myself to remember that this is not how it works. I suggest making "Shoot" and "Grab" the same button and putting "Drop" on a separate one.

Additionally:

Shoot" is called "Shoot" even though it also triggers melee weapons. How about "Attack"? or "Use weapon"?
