Title: added a 'do I own this page' check when remixing a page

this prevents the following scenario:

[A] publishes a page
[B] loads up the page /edit link
[B] hits publish
server sees this is a remix, and tries to update the page for B

because the page only exists for A, updating for B crashes thimble. No longer!
