Increase compatibility for IronPython

[tcalmant]

It seems that the "try-except ImportError" trick to have a code working with both Python 2 and Python 3 doesn't work well with IronPython.

It seems the except block should intercept both ImportError and AttributeError exceptions, as shows this trace, running "run_remote.py" :

Traceback (most recent call last):
  File "C:\Program Files (x86)\IronPython 2.7\Lib\importlib\__init__.py", line 37, in import_module

Many tests don't pass in IronPython 2.7. Main problems are:

• Bug (?) in socket.create_connection(): all tests based on network fail
• IronPython raises LightException instead of Import in some cases.
• Error using importlib:

  File "C:\Program Files (x86)\IronPython 2.7\Lib\importlib\__init__.py", line 38, in import_module
    return sys.modules[name]
KeyError: tests.framework.simple_bundle

Seems to be too much for next release: prepare it for iPOPO 0.5.8 ?

Commit cece594bde66a543ce6445ac409226ffeeea5416 corrects the KeyError exception when reinstalling a bundle. Pelix framework tests now succeed on IronPython.

iPOPO nearly succeed: a SystemError exception is raised in test_requirements.testRequiresMap:

Also, any test about ConfigAdmin raises the following exception:

Commit fd34a553080aee01afa025fb3f1597326db37b69 corrects the ConfigAdmin error: the exception was raised because a locale-aware error message was logged and captured by nose.

[tcalmant]

From commit e9b9613bb709398b679478e7d41a5548aa044080, all Pelix/iPOPO tests pass with IronPython !

Tests of remote services HTTP transports are skipped, as they are using multiprocessing, which isn't supported in IronPython.
