Causes the visual editor to ignore code within the ignore_code shortcode. Great at keeping advanced HTML,
Wherever you have code you dont want the visual editor to touch use the [ignore_code] shortcode.
This version also supports the [insert_php] and <?php tags, though for the PHP tag you will have to
start the first line with <?php // > With latter two codes you will have to separately install
plugins to get the dynamic PHP insertion functionality.
