setCustomhandlers

Further whittling away at differences between
Instiki's and the main branch of SVG-Edit.
Now, the saveHandler is set from within the calling
page.

If the editor was opened from Instiki, choosing "Save Image"
now closes the editor window. To leave it open was kinda confusing.

Also sync with latest SVG-Edit changes.
