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.
Pass the SVG to the editor, using
editor.svgCanvas.setSvgString(selected);
instead. (Suggested by Jeff Schiller)
Fix a bug with line and freehand tools caused
by activating foreignObject tool. (Again, fix
due to Jeff)
Sync with SVG-Edit.
They are now selectable, draggable, resizable
and rotatable.
The MathML content behave strangely when you
resize, but snaps back to its correct size when
you let go of the mouse.
(Resizing the MathML involves changing the font-size
on the containing foreignObject. No interface for
that, yet.)
