[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();
}
