Better error if nagios is not installed
better error messages
CSS - dashboard colors changed
/objectbrowser - refactor edit_object

Replaced edit_object with a new simpler method

Urls have also changed a little bit, and now use
querystring more

We deprecate the url : /edit/{objecttype}/{shortname} because
shortname can contain things that are incompatible with url strings

Instead the new way to edit an object by shortname is to use search
parameters:
/edit/?object_type=service&host_name=bla
status/index - fix indentation
top_navigation_bar - fix indentation
remove deprecated columns=False from status.utils
