Create a "soft" fail condition for arguments, which means that if an argument is part of a % placeholder in a URL, failing validation is not actually a failure IF there is some other action to take when validation fails.

#271240 by mschiff: pgsql compatibility, left() doesn't exist but substr() exists in both pgsql and mysql.

#273570: Work around a FAPI limitation that only lets me validate a given form once even though I need to validate it an arbitrary number of times.

Fix argument validator so that access() is handled properly like it is on the default argument type.

#274807: setting the validate fail action to summary was not informing the UI that a style plugin is needed.

Change the update button to "update default display" when you are changing values on the default display.

#274482 by aclight: Remove unnamed Apply button from filter values so that it does not later appear in URLs.

#274341 by mooffie: Check for the presence of template files so that we can tell if a template got renamed but theme registry was not cleared.

#270920 by mooffie: Add checkbox to feed displays to allow use of the site name for the feed title, in order to better duplicate the basic Drupal rss.xml capability.

#270892 by aclight (expanded by me): put default action and validator options in a fieldset to make the form less confusing.

Exposed filter memory was being trashed by a rewriting validate; also, exposed filters that decided not to participate weren't properly storing that status in session. This fixes both things.

Exposed filters needed to use $form_state[input] not $form[#post], which was causing the "remember" setting to fail intermittently; also, if filters are not overridden use the default display ID for session storage so that remembered filters can be shared across displays.

query::add_relationship was adjusting the join for the relationship prematurely; add_table will do that on its own.

Fix a problem with relationships that caused the adjust_join to sometimes not be run, thanks to a minor error in the join collapsing code.
