Remove gridify_*

We injected a gridify_list and gridify_cursor function into each jinja2
template that we render. This was used to split the list of media_entries
into batches of 5 for nicer table columns. However, jinja2 has a nice |batch
filter built in that does the job for us just as well with less code (on our side)

Less code=good

so let's merge this one.
