status/log - datepicker moved to snippet
state_history filter using pynag.Parsers.LogFiles

Before state_history did parsing itself instead of allowing
pynag.Parsers.LogFiles to do it while parsing the logfiles.
state_history Add datepicker

Affects issue #295
state_history remove a bunch of empty lines

If there were no service problems it would still output 2 newlines per
service.
