CLC-1075 in-progress 

JIRA: https://jira.media.berkeley.edu/jira/browse/CLC-1075

In-progress pull that separates the storage of notification raw data from its translation. We store raw data when we receive a JMS event (this is done by a "processor"), along with a string indicating the classname of the translator class.  At merged-model read-time, we apply this translator's transformation. 

This also connects notifications end-to-end so they can be seen in the UI. 

I tweaked the fake JMS feed so that test user 300846 would have a couple of events in his feed.
