Update the long pole

[bloodbowel]

Summary

Features "Updates the long pole"

Purpose of change

I noticed the recipe for the long pole is similar to the spear shaft in some ways. You could cut the period where the player watches oil soak into the wood. I also updated it's to-hit calculation and made it's construction more realistic using a long wooden post rather than a complete wooden beam.

Describe the solution

1. In #75640 I removed 4 hours from construction time by adding a soaking period. I did the same thing for the long pole here because the recipe is similar. Now those 4 hours are spent soaking while the player can go do something else.
2. I noticed that the long pole uses the old "to-hit: -1" to derive it's to-hit value. I updated this to use the modern grip/length/surface/balance calculation.
3. I noticed this item is created from the wooden beam which is way to thick for it. It now uses a long wooden post which is much thinner but not too thin. I increased it's recipe time to 2 hours and 40 minutes to reflect all the time needed to cut it into shape. That means to create this now takes 2 hours and 40 minutes in construction and 4 hours in a soaking state. So 6 hours and 40 minutes total.

Describe alternatives you've considered

Leave the long pole alone. Maybe adopt some of these changes and leave others.
