rename partisan -> partisan_(weapon)
These are all of the polearm variants that doesn't have an implication yet. I've left out some throwable spears (like javelin and pilum) and non-traditional ones like scythe, since it does not serve the function common to various polearms.
Also renamed partisan as a futureproofing, since the word "partisan" also means a group of anti-occupational forces.
