[RDY]Morale craft speed penalty

[Coolthulhu]

Currently there is no craft speed penalty for low morale, only a stonewall at -50 morale.
Changed to craft speed penalty for low morale.

The formula is as follows:

• If morale is not negative, no penalty
• For every skill requirement for a given recipe:
• • If crafter's skill is at least 2 times the requirement, no change
• • Otherwise multiply effective morale by 2 * requirement / crafter_skill
• Divide crafting speed by 1.0f + ( -effective_morale / 50.0f )
• If crafting speed is below 33%, you can't start a craft
• If crafting speed is below 20%, you stop current craft

The crafting speed is recalculated every single turn. This crafting speed also includes light penalty.
Important note: this change also means that losing light during crafting will now stop the activity!

The intentions are:

• Easy jobs (boiling water) will not be penalized noticeably
• Experts will have no problems with things trivial for them (ie. skill > 2 * requirement)
• Crafts that would increase skills are penalized the most
• You need non-negative (or at least only weakly negative) morale to effectively craft hard things

[CR] because both the formula and the intentions may be wrong.
Performance isn't perfect (it could be cached), but this shouldn't be costly enough to be noticeable, not even when repeated every single turn.

[WiP] because at the moment the penalty is applied twice - once for job length (at start of activity), once during crafting.

At last!

No more vehicle construction in the dark too?

Didn't change vehicle crafting or construction jobs, only item crafting.

Jenkins, rebuild

@Coolthulhu does this close #22203?

@Leland you mistakenly mentioned the current PR, I suppose.
