Rename Views method exposed_form_validate() to exposedFormValidate()

the last patch adds the public modifiers to the methods

The code looks good, but there seems to be something wrong with the BlockRenderOrderTest (very recently added)
I would mark this as blocked by http://drupal.org/node/1987952

Needs a re-roll
