38 hover icon

Fixes #38, cc @brson

Two quick fixes:
1) I removed the change to the whitespace of the static code section below. The editor actually renders twice: it does the `static-code` section then the `editor` section. Making these exactly equal speeds up the rendering of the page, and both of them render with the whitespace in the html file, so it needed to be removed.
2) The cursor is fixed by using `cursor: pointer` and `cursor: hand` for IE 5.5 and lower. Opera and Safari won't change the cursor unless the link has a valid href, so I pointed it to the null javascript value. 

IE compatibility might be broken altogether #40... Removing it would be fine with me.  For the reasoning here see http://www.quirksmode.org/css/user-interface/cursor.html
