Fix for Replace theme functions in live code.

  2.  * Clever hack to hide display of blocks during wizard.
  3.  *
  4.  * The wizard installation tries to keep things as simple and uncluttered
  5.  * as possible, making basic use of the menus and forms.
  6.  *
  7.  * This uses eval to replace the theme_block function implementation.
  8.  * It's done this way so it doesn't affect the interface of the rest
  9.  * of the site, and just clicking on home will make the site render
  10.  * normally.
  11.  *
  12.  * Only way this could break is if the theme already had a $theme_block,
  13.  * which i consider unlikely, as most themes are phptemplate based these days.
  14.  *
  15.  * This could probably work for a number of theme functions.
