Problem with unescaping class arguments

I've got an error when I tried to use DI to initiate Monolog logger with next settings:

services:
  logger_formatter:
    class:        \Monolog\Formatter\LineFormatter
    arguments:    [ "[%%datetime%%] %%channel%%.%%level_name%%: %%message%% %%context%%\n" ]  
  logger_handler:
    class:        \Monolog\Handler\StreamHandler
    arguments:
      - app.log
      - <?php echo \Monolog\Logger::DEBUG, PHP_EOL; ?>
    calls:
      - [ setFormatter, [ @logger_formatter ]]
  logger:
    class:        \Monolog\Logger
    arguments:    [ 'logger_name' ]
    calls:
      - [ pushHandler, [ @logger_handler ]]

If I set argument for service logger_formatter with single % (like "[%datetime%]…") then DI threw exception that it could not resolve reference because there was non-existent parameter "datetime". If I set argument with double % (like "[%%datetime%%]…") then DI transferred parameter to the LineFormatter object without unescaping, and LineFormatter did not work properly. The problem was in ContainerBuilder, because there was no unescaping class parameters.

I’ve fixed problem and added tests to cover such case.

Allow get parameters by path, separated by colon

For example:

app/config/parameters.yml

parameters: social: facebook: app_id: 1234567890

Now it's possible to get app_id like: $this->get('social:facebook:app_id');

The colon symbol ":" don't allowed for use in parameter name and it's the most appropriate symbol for separator. At last we get more conveniently for get nested arrays value.

XmlDumper doesn't write factory-class attribute.

Symfony\Component\DependencyInjection\Dumper\XmlDumper didn't write 'factory-class' XML attribute for definitions on which setFactoryClass() was set.

This caused the Container[Builder] to throw an exception when the relevant service is being requested/initiated after loading the dumped XML:

Uncaught Exception Symfony\Component\DependencyInjection\Exception\RuntimeException: "Cannot create service "xxx" from factory method without a factory service or factory class." at /<path>/<to>/vendor/symfony/dependency-injection/Symfony/Component/DependencyInjection/ContainerBuilder.php

Fixed the problem, and updated relevant test fixture.

[DependencyInjection] Extend TaggedIterator and TaggedLocator Attributes with able to specify defaultIndexMethod for !tagged_iterator or ServiceLocator

Just extended two attributes that do not break compatibility, are optional and null. The feature only allows you to do almost the same as in YAML files, the configuration specifying defaultIndexMethod for:

\ Symfony \ Component \ DependencyInjection \ Attribute \ TaggedIterator
\ Symfony \ Component \ DependencyInjection \ Attribute \ TaggedLocator

Added more examples to README.md

I added a few more examples covering use of addMethodCall(), setFactoryClass/Method(), and setFile().
