Subject: [PATCH] fix to prevent javascript:void(0) anchors breaking
 placeholders in IE

- fixes  #74
- fix to prevent javascript:void(0) anchors breaking placeholders in
IE. javascript:void(0) causes beforeunload to fire off causing the
plugin to clear placeholders. We try to check to see if
javascript:void(0) is being used by calling document.activeElement
