Add management command to save the year to events in ES

A management command that adds a year field to the events in
ElasticSearch was added to the corpus app. The command finds all
text_ids in the ElasticSearch index and looks up the first year of
publication of a title. Than all events are retrieved for a title and
a new field containing the year as an integer is added. If a title
contains multiple titles, no years are added, because it is not clear
which title is needed. This somehow needs to be fixed later. In the
collection of titles selected for annotation no multiple titles are
contained, so the problem does not occur.
Add management command to save genres and subgenres to events

A management command was added that saves the genre and subgenre
information to events in ElasticSearch. Genre(s) and subgenre(s) are
added as a list of tags. The genre and subgenre information will be
used to create data for visualizations.
Add url mapping and view for displaying information about speakingturns

Added an url mapping and view for displaying information about
speakingturns. Speakingturns are selected based on a list of words. The
list of words is still hardcoded, this needs to be changed later. The
information extracted is the number of documents (events) for each word
in the list, the speakingturns containing the word, and word frequencies
of words in the speakingturns.
Add template to display information about speaking turns

Added a template to display the information about speakingturns.
Update url mapping and view to display info for different concepts

Previously, the find_in_speakingturns view returned information about a
list of words that was hardcoded. The view now contains a dictionary
containing lists of words that are spelling variants of a concept. The
url mapping was updated to accept an additional parameter that specifies
the concept to be searched for. Based on this argument, the view
returns information for the appropriate list of spelling variants.
Update template to display the concept in the title

The speakingturns template was updated to display the concept searched
for in the title.
