datasette.add_memory_database() method

[simonw]

I just wrote this code:

datasette/tests/test_facets.py

Lines 334 to 335 in 47eb885

	ds = Datasette([], memory=True)
	db = ds.add_database(Database(ds, memory_name="test_json_array"))

It would be nice if you didn't have to separately instantiate a database object here.

A couple of options:

datasette.add_memory_database("test_json_array")
# or make that first argument to add_database() optional and support:
datasette.add_database(memory_name="test_json_array")

I like the .add_memory_database() option. I also like that it makes it more obvious that this is a capability of Datasette, since I'm excited to see more plugins, features and tests that take advantage of it.
