Worked on docs/tickets/67.

• New view lino.ui.extjs3.views.PlainIndex

• The detail of a row now renders something. This needs lots of fine-tuning, but for a proof of concept that’s enough now.

• lino.ui.base.UI.get_patterns() now adds a single pattern instead of one pattern for each pages.Page.

• Changed admin_url to lino.Lino.admin_prefix.

TODO: The ADMIN_URL variable in linolib.js doesn’t correctly handle the case of an empty admin_prefix.
