Edit Form generates "url not set" error before importing ajaxEditOptions

[dvdotsenko]

Was playing around with Form Editing and found what I think is a bug.

I am trying to use generic ajaxEditOptions (with serialization callback code injecting extra data into postdata) for all of my Edit Forms. (It is easier this way to create multiple instances of grid for me.)

I am not populating "url" (or "editurl") property of the grid at all. I wanted to use one and the same url and options as taken from a "shared" ajaxEditOptions. But as per last commit sha: 17c4749 grid's Edit Form code presents an error complaining about unset URL before it imports settings from ajaxEditOptions.

Lines 859-861 (grid.formedit.js) trigger an "URL is not set" error, before $.jgrid.ajaxOptions and rp_ge.ajaxEditOptions are merged into the ajax properties.
