Add stamina cost info to melee weapon descriptions

[metalheimer]

Is your feature request related to a problem? Please describe.

This probably should've existed since day one. It would certainly help compare melee weapons.

Describe the solution you'd like

Two additional lines to descriptions, suggested below the "moves per attack" line.

Stamina cost (base): 123
Stamina cost (with modifiers): 132

or Stamina cost (actual): 132

Additional context

Include stamina info in character sheet. Max stamina, base stamina regen rate and current modified stamina regen rate.

idk, i feel that is like a good idea, but not that necessary, i think that if there is going to be more info cluttered in the item description/comparation it should be the hit chance

Lines 653 to 664 in a5e79b7

	// Previously calculated as 2_gram * std::max( 1, str_cur )
	const int weight_cost = cur_weapon.weight() / ( 16_gram );
	const int encumbrance_cost = roll_remainder( ( encumb( bp_arm_l ) + encumb( bp_arm_r ) ) *
	2.0f );
	const int deft_bonus = hit_spread < 0 && has_trait( trait_DEFT ) ? 50 : 0;
	const float strbonus = 1 / ( 2 + ( str_cur * 0.25f ) );
	const float skill_cost = std::max( 0.667f, static_cast<float>( ( 30.0f - melee ) / 30.0f ) );
	/** @EFFECT_MELEE and @EFFECT_STR reduce stamina cost of melee attacks */
	const int mod_sta = -( weight_cost + encumbrance_cost - deft_bonus + 50 ) * skill_cost *
	( 0.75f + strbonus );
	mod_stamina( std::min( -50, mod_sta ) );
	add_msg( m_debug, "Stamina burn: %d", std::min( -50, mod_sta ) );

might be tricky to implement. proceeds to blame spaghetti code
