322787470,MDU6SXNzdWUzMjI3ODc0NzA=,259,inspect() should detect many-to-many relationships,9599,closed,0,,,6,2018-05-14T12:03:58Z,2019-05-23T03:55:37Z,2019-05-23T03:55:37Z,OWNER,,"Relates to #255 - in particular supporting facets across M2M relationships.

It should be possible for `.inspect()` to notice when a table has two foreign keys to two different tables, and assume that this means there is a M2M relationship between those tables.

When rendering a table with a m2m relationship we could display the first X associated records as a comma separated list of hyperlinks in a new column on the table view, with a column name derived from the table on the other side.

Since SQLite doesn't have RANK or an equivalent of https://www.xaprb.com/blog/2006/12/02/how-to-number-rows-in-mysql/ this would be implemented as N+1 queries (one query per cell that we want to display an m2m summary).

This PR is just to gauge if this, or something like it, is something you would consider merging?

I understand the reason why the substring of the hash is included in the url but
there are some use cases where the urls should persist across deployments. For bookmarks
for example or for scripts that use the JSON API.

This is the initial commit for this feature.
