Replaced "botpopstop" plugin + added Tank anti-rock protect on his spawn

[BRU7U5]

• Deprecated "botpopstop" plugin and replaced by "l4d2_block_bot_pills"

This plugin blocks bot from using pills using "Actions" extension.

• Added "l4d2_tank_spawn_antirock_protect"

This plugin blocks a Tank player from randomly activate throw attack after his spawn.

Very nice suggestion of the anti-rock one, relatable mistake I've made many times. 😅
I'll gladly accept the PR once I've ran a few tests on the block bot addition, I'm unsure about a few things with it.

Of course, thanks! If you need help with testing or making changes to this PR - I'm willing to help.

Nice works! Some minor suggestions here.

1. L4D2-Competitive-Rework/addons/sourcemod/scripting/l4d2_block_bot_pills.sp

   Line 41 in 17676b9

   if (strcmp(name[8], "TakePills") == 0)

   
   It's probably true that no action's name is below length of 8, at least in official. But some custom actions created by plugins could probably be that case. Gotta take care of them and avoid potential errors at here.

2..

L4D2-Competitive-Rework/addons/sourcemod/scripting/l4d2_tank_spawn_antirock_protect.sp

Lines 29 to 35 in 17676b9

	public Action L4D_OnCThrowActivate(int ability)
	{
	if (GetGameTime() - g_fSpawnTime < g_cvAntiRockProtectTime.FloatValue)
	return Plugin_Handled;
	return Plugin_Continue;
	}

Generally there's only single tank across the whole map flow for most maps, except Dead Center 4 where there could be double tanks. This might unexpectedly block rock attempts of previous tanks whenever a new tank spawns.

Thank you very much for the good suggestions! I will try to fix potential problems quickly as soon as I have free time

Apologies for getting back to you so late, a hunch I had was that this wouldn't prevent Survivor Bots from taking pills if they had the pills in-hand while a threat was in the area.
After testing, the bots will indeed still instantly take the pills when in-hand as they replace a player (which may be unintentional as they could've been wanting to pass pills before crashing)

I've added a simple method to prevent the bot from taking the pills instantly while also adding a full check for SurvivorTakePills which should resolve @jensewe 's valid concerns 😄

I've also gone ahead and addressed the possible issue within l4d2_tank_spawn_antirock_protect.
