#1230306 by aaron.r.carlton, dereine: User and taxonomy default plugin updated to new behaviour of views_get_page_view

#1207680 by damz: Don't validate if there are no options set, the values are empty and required is not set

Issue #1207680 by dereine: Don't validate on term filters, because this causes views to not to save anymore. Added TODO

#1147326 by becw, dereine: Add a way to reverse transforming of argument values back to the original value, so you can use it for the summary. For example you can have now user: uid as argument but still have nice username urls.

Issue #1182762 by tim.plunkett: Remove periods in sentences on checkbox titles, as they are counter to UX standard.

by dereine: don't display the summary asc by count, sumamry desc by count on the termi depth handler

Use the term_tid filter handler on field term filters, modified slightly to restrict vocabulary correctly.

#975400 follow up by bojanz: Give field::sanitize_value more power and fix some issues with get_value.

The position of elements on the filter edit dialog now matches the mockups. A few paddings here and there, and we're done.

Rename optional to required (filter expose settings). Kill the division of the expose settings form into left/right, makes no sense in the new UI.
