Rename Views method render_exposed_form() to renderExposedForm()

Patch for review.

#2: 2003346-render_exposed_form.patch queued for re-testing.

Previous test failed because it failed to checkout from git. I'm hoping that was just a result of so many patches being submitted at the same time during the Drupalcon Portland code sprint.

Okay. Passed this time. Ready for review.

Add public access modifier in front of the function to adhere to the new OOP standards.

Alrighty then. Public access modifier added to front of the function to adhere to the new OOP standards and re-rolled.

Looks good to me now !
