Added a form to update a named view + word of warning. Hooked it into the change button on the view's page.
Added the update function, changed the update form a little bit and fixed the typo (where the http method name was update instead of put)
Fixed a bug in redirect after update. Also changed PUT to POST since not all browsers support PUT
Added test case for renaming a view
Merge remote-tracking branch 'origin/master' into 477-rename-views-from-ui
Put the update button into a paragraph to give it some room.
