Livestatus crash with non-ascii characters

[Florent Lerat]

When the livestatus module is attempting to output non-ascii characters, it crashes. Such caracters can be found in macros.

In this case, the issue was caused by the character ü.

Adding the following lines after the imports to the file "/var/lib/shinken/modules/livestatus/livestatus_response.py" fixed the issue.

import sys  # import sys package, if not already imported
reload(sys)
sys.setdefaultencoding('utf-8')
