YAMLParser now supports YAML lists not parsed by the parser itself.

This means that list of type
```yaml
list:
  - test: "Hello"
  - test: "Hi"
```
will be parsed as a list of (ConfigurationSection)[src/main/java/it/fulminazzo/yamlparser/configuration/ConfigurationSection].
Totally reworked classes separation to respect packaging conventions.
Reworked FileConfiguration#addParsers method.
Renamed `it.fulminazzo.yamlparser.configurations` package to `it.fulminazzo.yamlparser.configuration`.
Made FileConfiguration and ConfigurationSection final.
Updated README.md
