[migration] move 'entities' table changes from 3.19.0 to bootstrap script The 'mtime' and 'source' columns need to go away before we attempt to do anything else with the repo, otherwise any addition of an entity is going to explode.

RSS Channel
-----------

Assuming you have several blog entries, click on the title of the
search box in the left column. A larger search box should appear. Enter::

   Any X ORDERBY D WHERE X is BlogEntry, X creation_date D

and you get a list of blog entries.

Click on your login at the top right corner. Chose "user preferences",
then "boxes", then "possible views box" and check "visible = yes"
before validating your changes.

Enter the same query in the search box and you will see the same list,
plus a box titled "possible views" in the left column. Click on
"entityview", then "RSS". 

You just applied the "RSS" view to the RQL selection you requested.

That's it, you have a RSS channel for your blog.

Try again with::

    Any X ORDERBY D WHERE X is BlogEntry, X creation_date D, 
    X entry_of B, B title "MyLife"

Another RSS channel, but a bit more focused.

A last one for the road::

    Any C ORDERBY D WHERE C is Comment, C creation_date D LIMIT 15
    
displayed with the RSS view, that's a channel for the last fifteen
comments posted.

* show that the RSS view can be used to display an ordered selection
  of blog entries, thus providing a RSS channel

* show that a different selection (by category) means a different channel
