the first part of the page editing API is working again after porting it over
form the old fipamo build. a few changes where made to make the code a
big more managable, but the end to end process works for updating pages.
the remaining page editing methods will be activated after the rendering
engine is in place because that's going to be a pretty siginficant
effort.
but this is a big step.
start building out the new version of the page editing api while making
some changes to the original scripts for added flexibility and using the
full range of HTTP methods that weren't being used before.
currenlty, it's just an end to end test to make sure the plumbing works
as it should data is being passed and can be processed.
now that it all works, the guts of page editing can be completed
update sortablejs to the latest since it's been awhile and got rid of
the old version
