[Radiant] ajax call for "save and continue editing" and style changes

[Steven Southard]

I've been using this interface a lot lately and one thing that would  
make it much better for me is not having the page refresh when I hit  
"save and continue editing".  This is especially true when I'm editing  
a long CSS file, I hate to image how much time I wasted looking for  
the place I was just editing.  A couple of other default style changes  
I think would help are to make the text area height about 600px also a  
bit skinnier and over to the right so I can grab the side easier and  
get to the save changes button.  Having to scroll down the page like  
that to get to the save button is kind of a pain as well.  I think the  
save button would be more useable if it were in that blank space to  
the right above the text area.

Regards,
