Updated canvas setup callback to reference shared code with islandora_image_annotation, in its includes/utils, results are echoed. Updated the startup.js to utilize the new manifest url, as the callback function now returns a fully qualified url, and needs no javascript concatenation anymore.
Shared function name changed in islandora_image_annotation, updated the callback fuction here to reflect the recent changes.
