Typo corrections
Moved 0.5.4 release notes to CHANGELOG
get_*_service_references(): LDAP filter set to None by default

get_service_references() and get_all_service_references() now work like
get_service_reference().
Added utility context use_service(context, ref)

Like use_ipopo(context), but for any service reference: allows to use a service easily in a 'with' block.
Raises a BundleException in case of error, and a type error if the reference is invalid.
Log all shell command exceptions
Force new line when quitting the shell console
First implementation of the HandlerFactory pattern
PropertyHandler has no kind, so it is no stored by StoredInstance

Avoids to notify a handler for nothing.
ServiceRegistrationHandler: only work with the handler's controller

Avoid updating the state of all controllers in every handlers.
iPOJO Core keeps track of the HandlerFactory services with a listener

Speeds up the search for factory services, as they are already in a
dictionary (avoids the LDAP filter parsing/testing).
Ignore profiling files

FactoryContext holds the Handlers configuration

- Decorators use this place to store their configuration, instead of
  having specific FactoryContext class fields
- Factory context is stored in its bean form instead of a dictionary
  form (to allow special types in handlers configuration)
- Code still to be cleaned up a bit
Contexts: code clean up

- Removed dictionary form methods
- Removed previous specific fields for requires and provides
- Added custom support of deep copy in Requirement
Removed dictionary form of FactoryContext

The FactoryContext bean is stored as is in manipulated class, instead of
being converted in a temporary dictionary.
The "factory context data" field (containing the dictionary) has been removed.
Call RequestHandler.finish() when exiting RemoteShell loop
Added a missing return...
iPOPO Core ignores classes with a partial FactoryContext

Case of parent classes of some factories, e.g. with an iPOPO property
decorator, but no factory name.
