Add information about target selectors to our reporting annotation table

[jon-betts]

For:

• Summaries of annotation types for an organization report#231

This adds info about target selectors, which will allow us to work out if things are page notes / highlights etc.

Note! This will take some care to release, as we need a full re-index of the annotations, which will probably take a while.

Open questions

• Is there any value in storing the number of target_selectors vs a boolean?
  • Nope, not really. More details here.

Testing notes

• Start Via, ViaHTML, Client etc.
• Visit: http://localhost:9083/http://example.com/
• Make a few annotations of various types
• Run report/create_from_scratch
• make sql

SELECT * FROM report.annotations

• You should see the different booleans set
• Run fast_recreate
• Run refresh
• Hopefully nothing asplodes

DO NOT MERGE

When this is ready, it will take a bit of timing to run the create from scratch. This took 45 minutes before and could easily take longer now. When that is done we should do the fast recreate and finally an update.

This should be done so as to avoid the normal update window for H + LMS + Report.

Looks good, let's see how long the from scratch process takes this time.
