Uses https://pluggy.readthedocs.io/ originally created for the py.test project
We're starting with two plugin hooks:
prepare_connection(conn)
This is called when a new SQLite connection is created. It can be used to register custom SQL functions.
prepare_jinja2_environment(env)
This is called with the Jinja2 environment. It can be used to register custom template tags and filters.
An example plugin which uses these two hooks can be found at https://github.com/simonw/datasette-plugin-demos or installed using `pip install datasette-plugin-demos`

This also stops it filling up the logs. This happens for HEAD requests
at the moment - which perhaps should be handled better, but that's a
different issue.
This renders unlabeled FKs as simple links. I can't see why this would
cause any major problems.
Also includes bonus fixes for two minor issues:
* In foreign key link hrefs the primary key was escaped using HTML
escaping rather than URL escaping. This broke some non-integer PKs.
* Print tracebacks to console when handling 500 errors.
This fixes `ERROR: conn=<sqlite3.Connection object at 0x10bbb9f10>, sql
= 'select ', params = {'id': '1'}` caused by an invalid query when
loading incoming FKs.
The error was ignored due to async but it still got printed to the
console.
We now display sort options as a select box plus a descending checkbox, which
means you can apply sort orders even in portrait mode on a mobile phone where
the column headers are hidden.
Closes#199
You can now explicitly set which columns in a table can be used for sorting
using the _sort and _sort_desc arguments using metadata.json:
{
"databases": {
"database1": {
"tables": {
"example_table": {
"sortable_columns": [
"height",
"weight"
]
}
}
}
}
}

Verifies that they match an existing column, and only one or the other option
is provided - refs #189
Eses a new DatasetteError exception that closes#193
New _shape= parameter replacing old .jsono extension
Now instead of this:
/database/table.jsono
We use the _shape parameter like this:
/database/table.json?_shape=objects
Also introduced a new _shape called 'object' which looks like this:
/database/table.json?_shape=object
Returning an object for the rows key:
...
"rows": {
"pk1": {
...
},
"pk2": {
...
}
}

If you set the source_url/license_url/source/license fields in your root
metadata those values will now be inherited all the way down to the database
and table templates.
The title/description are NOT inherited.
Also added unit tests for the HTML generated by the metadata.
