[CoC] Add HUD animation speed parameter support in ltx files.

[Neloreck]

Still testing it while integrating some weapons from CoC/anomaly. Without it game crashes on assertions / has de-synced sounds.

Changes

• Adding support of third parameter in weapon hud sections, CoC and anomaly uses it everywhere

Examples

anm_idle = protecta_idle
anm_idle_aim = protecta_aim
anm_idle_aim_moving = protecta_move, idle, 0.75
anm_idle_aim_moving_crouch = protecta_move, idle, 0.7
anm_idle_moving = protecta_move
anm_idle_sprint = protecta_sprint

anm_idle_moving_crouch_w_gl_aim = sg550_crouch_w_gl
anm_idle_moving_g = sg550_move_g
anm_idle_moving_g_aim = sg550_move_g, idle, 0.75
anm_idle_moving_w_gl = sg550_move_w_gl
anm_idle_moving_w_gl_aim = sg550_move_w_gl, idle, 0.75

The code below requires at least one parameter, and uses additional two.
It's more logical to use this condition:

Suggested change

	R_ASSERT2(_GetItemCount(anm.c_str()) <= 3, anm.c_str());
	R_ASSERT2(_GetItemCount(anm.c_str()) > 0, anm.c_str());

[Neloreck]

Logics before:
1 parameter - use name as base and additional parameter
2+ parameters - assert it is only 2 params and read both

Logics after:
1 parameter - same as before
2+ parameters - make sure it is either 2 or 3 parameters, if someone leaves empty space and wants to only add animation speed

---

Seems like:
1 - adding < 0 assertion and storing count as variant makes sense
2 - probably I should add trimming for pm.m_additional_name strlen check? Or parser of comma separated values already does it? Will need to check it

[Xottab-DUTY]

Can we reuse this somehow? We still support multiplayer.

[Neloreck]

This util used for two different classes. Can add one more param to use as base and keep it pure function or copy-paste as separate methods/util functions. Sounds like first variant is better

[Neloreck]

Updated util / excluded non-singleplayer games from animation speed calculations.
