Bulk indexing respects --index parameter

Sheer will now pass in the --index parameter (whether supplied by the user or the default) when performing bulk indexing.

Add when() function to template context

A when() function has been added in order to determine whether the two arguments given (starttime and endtime) describe a period of time in the past, present, or future, in which it returns the absolute tense as one of those strings.

Add Timezone parameter to date formatter filter function

Timezones are now being used for the date formatter filter function so they can be displayed on the front-end. The default timezone is Eastern.

Fixes search bug, changes search function name

This changes the search function name from search_with_url_parameters to search and fixes a bug that makes all filter arguments trigger for a given template context instead of just the ones that are intended for the query.

Upgrade dependency 'six'

Having an old version pinned was conflicting with unittest2, an eleasticsearch-py dependency when running on Python 2.6. Hopefully we cal leave 2.6 behind soon, but not today.

Exit Code for Indexing Failure
