url refactoring

status.views.status_detail renamed to status.views.detail

status.views.detail is now a wrapper for contacts contactgroups etc,

in addition to hosts and services that it was before

refactored all calls to contact_detail to use detail?contact_name=X instead
Refactor urls to hostgroup details

change all adagios.status.views.status_hostgroup to
adagios.status.views.detail?hostgroup_name=X
cleanup in status/urls.py
