"vertical" resize_dir still sets width CSS

[Leonard Lee]

When resize_dir is configured to be "vertical", only vertical size changes should be allowed. However, after some vertical resizing, a width CSS style (in px) is set on the editor span. For example:

style="width:1019px"

This is a problem if the editor is supposed to be 100% wide. The editor is now stuck at being the same width, even when the window/container resizes.

The same issue probably applies to "horizontal" resize_dir, but with a height CSS style.

Both issues can be fixed by changing the editor resize function call in resize/plugin.js to:

editor.resize( resizeHorizontal ? width : null, resizeVertical ? height : null );

This will cause the width/height to only be changed when necessary.
