title: Proper way to dispose screens in Libgdx
body: <p>What is the proper way of completely disposing of a screen in Libgdx? Currently If I click where a button was on my previous screen the button still does what it would of done if I were on that screen. Should I be <code>.dispose()</code>-ing everything I can in the <code>dispose()</code> method? or is there a simpler way to dispose of everything on screen?</p>
