Icon

this ended up more than the icon.  

* svg icon
* overflow:hidden on .app to prevent iphone scrolling shenanigans. 
* overflow:hidden on a codemirror div to prevent similar.  
* add a name property to menus
Won't this run both `scripts` and `scriptsWatch`?  It seems like having two tasks outputting the same file (esp. asynchronously) might not be a good idea.
