In preparation for the item form feature, I've added and tried to improve a few
thing. The new hero page style of brown and blue is growing on me.

- Added hero class parameter to item forge link on the hero page.
- Removed JavaScript to pull item form in via AJAX.
- Added PHP include to pull the item form directly into the get-hero page.
- Refactored item form JavaScript.
- Updated hero page styling.
- Updated image processor to handle image URLs in the CSS, support for jpg and gif were added.
- Added new tool to display the a hero's highest completed level and act.
- Updated hero JSON sample.
- Fixed bug with getHtmlInnerBody method.
