Rename certain namespaces, interfaces and classes.

Now we follow a Symfony2-like naming convention for namespaces, interfaces
and classes sticking with one clear rule.

- Renamed namespaces:

  - Predis\Network
  - Predis\Profiles
  - Predis\Iterators
  - Predis\Options
  - Predis\Commands
  - Predis\Commands\Processors

- Renamed interfaces:

  - Predis\IReplyObject
  - Predis\IRedisServerError
  - Predis\IConnectionFactory
  - Predis\IConnectionParameters
  - Predis\Options\IOption
  - Predis\Options\IClientOptions
  - Predis\Profile\IServerProfile
  - Predis\Pipeline\IPipelineExecutor
  - Predis\Distribution\INodeKeyGenerator
  - Predis\Distribution\IDistributionStrategy
  - Predis\Protocol\IProtocolProcessor
  - Predis\Protocol\IResponseReader
  - Predis\Protocol\IResponseHandler
  - Predis\Protocol\ICommandSerializer
  - Predis\Protocol\IComposableProtocolProcessor
  - Predis\Network\IConnection
  - Predis\Network\IConnectionSingle
  - Predis\Network\IConnectionComposable
  - Predis\Network\IConnectionCluster
  - Predis\Network\IConnectionReplication
  - Predis\Commands\ICommand
  - Predis\Commands\IPrefixable
  - Predis\Command\Processor\ICommandProcessor
  - Predis\Command\Processor\ICommandProcessorChain
  - Predis\Command\Processor\IProcessingSupport

- Renamed Classes:

  - Predis\Commands\Command
  - Predis\Network\ConnectionBase

- Classes moved to different namespaces:
