[Suggestion] Map Prefix Support

[MAGNAT2645]

Would be good to have map prefix support, so we don't have to put most stuff in global_filters.cfg and just use configs like koth_.cfg (any koth maps), ctf_covid19_.cfg (any version of ctf_covid19) etc.

In my case, i want to play FF2 on koth maps, so i put:

modify:
{
	match:
	{
	"classname" "tf_logic_koth"
	}
	replace:
	{
	"classname" "tf_logic_arena"
	}
}

into global_filters. BUT i have cp_sulfur map which is koth + cp hybrid so that map has tf_logic_koth. Stripper replaces it to arena mode too but i don't want arena on cp_sulfur.

For now i have this workaround:
addons/stripper/maps/cp_sulfur_rc2.cfg

modify:
{
	match:
	{
	"classname" "tf_logic_arena"
	}
	replace:
	{
	"classname" "tf_logic_koth"
	}
}

Good idea. Don't have any reason for me to implement and test it myself, but I'd be happy to take the PR for it.

If you'd like to give this a try, I have a function for prefix-based file detection in use here, which can then be injected at this location in the plugin.

There's also a code from MapConfig with prefix support:

#define CONFIG_DIR "sourcemod/map-cfg/"

void ExecuteMapSpecificConfigs() {
	char szConfigFile[PLATFORM_MAX_PATH];
	ArrayList hConfigs = new ArrayList( PLATFORM_MAX_PATH );

	{
		char szCurrentMap[PLATFORM_MAX_PATH];
		GetCurrentMap( szCurrentMap, sizeof szCurrentMap );

		{
			int iMapSepPos = FindCharInString( szCurrentMap, '/', true );
			if ( iMapSepPos != -1 )
				strcopy( szCurrentMap, sizeof szCurrentMap, szCurrentMap[iMapSepPos + 1] );
		}

		LogMessage( "Searching specific configs for %s", szCurrentMap );

		DirectoryListing hDir = OpenDirectory( "cfg/" ... CONFIG_DIR );
		if ( hDir == null ) {
			LogError( "Error iterating folder cfg/" ... CONFIG_DIR ... ", folder doesn't exist !" );
			return;
		}

		char szExplode[2][64];
		FileType nFileType;

		while ( hDir.GetNext( szConfigFile, sizeof szConfigFile, nFileType ) ) {
			if ( nFileType != FileType_File )
				continue;

			ExplodeString( szConfigFile, ".", szExplode, 2, sizeof szExplode[] );

			if ( strcmp( szExplode[1], "cfg", false ) == 0 ) {
				if ( strncmp( szCurrentMap, szExplode, strlen( szExplode ), false ) == 0 )
					hConfigs.PushString( szConfigFile );
			}
		}

		hDir.Close();
	}

	hConfigs.Sort( Sort_Ascending, Sort_String );

	for ( int i = 0, size = hConfigs.Length; i < size; i++ ) {
		hConfigs.GetString( i, szConfigFile, sizeof szConfigFile );
		LogMessage( "Executing map specific config: %s", szConfigFile );
		ServerCommand( "exec " ... CONFIG_DIR ... "%s", szConfigFile );
	}

	hConfigs.Close();
}
