Implement support for a "form" mode

[ChrisABryant]

Looks far better than previous json editors we've used! Color picker and boolean checkboxes were exactly what I was looking for.

Two things as we have a static structure that we only want to be able to change values and not schema. Used the following css with the jse-no-context class applied to the wrapper div. This prevents display of the context menu as well as attempts to edit the object keys. Would be nice if there were some prop flags for contextMenu and editableKeys.

.jse-no-context {

   .jse-contextmenu {
      display: none !important;
   }

   .jse-context-menu-pointer-anchor {
      display: none !important;
   }

   .jse-context-menu-pointer {
      display: none !important;
   }

   .jse-insert-area {
      display: none !important;
   }

   .jse-key {
      pointer-events: none;
      cursor: pointer;
   }

}

Thanks Chris, good to hear you like the editor :)

The editor doesn't cater at all for the use case you describe, basically a "form" mode.

It requires require control over what built-in actions are enabled/disabled, like insert, duplicate, remove, etc. And it requires customizing the buttons in the context menu, see #82. And it would require having read only keys but editable values. We have to investigate what it involves exactly and how to go about it.

If there is anyone interested in thinking this though?
