fix macroresolver error from eltdetail template

Define output_macros as a class variable instead of an object variable
Fixes problem found in shinken-monitoring/mod-webui#88
Added HTTP call: get_start_time
start_time is now an int
LogEvent: Added pattern for FLAPPING events
Use start_time in running_id
Fixed issue where running_id's random number was always 0
Included importlib for python2.6.
Py26: Still try to load importlib from system before fall back on our copied one.
Why not (re-?)enable travis for 2.6 while we are at it ?
py2.6 str.encode() does not accept keyword argument.

Fix: dummy commit to force a build on travis and coverage (coveralls.io)
Add: coveralls.io data to send coverage information
Fix: seems that coverage and nose and multiprocess are not happy, lets give a try with single process, seems to go to the end
Fix: travis tests until nose is happy again
