Changed In Process label to In Progress in entity and collection models.
break out search reindex view code so other views can use it.
trigger local search reindex when drives are mounted/activated

Prevents local search from working with stale data.
update local search index for collection on collection sync
storage decorator reports when ddr base symlink is missing

Before it just errored, but now it displays a message more
clearly presenting the problem.
insert task start as str to prevent JSON serialization errors

This was not a problem before, but Celery started complaining
that it could not serialize the task['start'] datetime to JSON.
To avoid the error, task['start'] is now inserted as a str
using TIMESTAMP_FORMAT.  The task list template still needs a
datetime, so this is created in the function that lists tasks
for that page.
Merge branch 'master' into 099-inventory
