Forgot to update the package version to 0.5.2
Enhanced Python 3 compatibility

- Using str(ex) instead of ex.message to print ValueError exceptions
HTTP: Servlet exceptions are now logged

Servlet exceptions are now both sent to the client and logged using the
HTTP bundle logger.
Shell output is now flushed

- Flush forced in IOHandler.write_line() (doesn't seem to work...)
- Flush forced on prompt on the console output (works well)

=> Allows to have a correct output of a Pelix shell inside Eclipse (for example)
New "factory" shell command

Prints details about an iPOPO factory, like its default properties,
requirements, provided services.
Remote Services: Correction for Python 3

A conversion from bytes to str was missing
Ignore Eclipse settings
Version number update -> 0.5.3
Added release notes of 0.5.3
