Change cursor of Spacemacs from box to vertical line for all themes
<p>I have installed some themes for Spacemacs, and some of them make the cursor appear as a vertical line (like in Sublime or Atom), while some make the cursor appear as a solid box (like the default theme of Spacemacs).</p>

<p>Is there any way to set the cursor appearance to a vertical line for all themes?</p>
