New view objectbrowser/add_to_group

Use this to quickly add lots of services to a contactroup

Work in progress
Fix inefficiencies in javascript and readability

Using jquery selectors multiple times to find the same elements is
inefficient and was replaced with 2 new variables.
Merge branch 'master' into celery_integration
code cleanup
okconfig_.views - add docstrings to view methods

@tomas-edwardsson was confused what the functions here do and asked for docstrings.
objectbrowser.views  - add docstring to views.
Enable bulk edit/delete/copy from status view

Bulk views now are able to take shortnames as input as opposed
to pynag IDs

Also change format of the clock in top navigation bar
Merge branch 'master' of github.com:opinkerfi/adagios
Enable select2 type hidden
okconfig - base template switched back to base2
status/hostgroup/X - action buttons now enabled
/status/perfdata - update querystring handler

Before it had a primitive implementation, but now
it uses the same querystring parameters as other status views.

Fixes #225
status/hostlist - use last_check instead of last_state_change to determine pending status

I am not quite sure why last_state_change was chosen to check if a check has ever been run on a host or not, but for some reason if host has no services, last_state_change will not update from 0.

Fixes #222
Top navigation bar timestamp now timezone aware

Previous implementation used time.time() now we are using datetime.

Fixes #224
Merge branch 'master' into celery_integration
