Update Build directory to latest version
Better build process

Previously, the build process relied on the images and diva serve scripts being permanently available in the build/ directory. Building diva via `fab release` will now copy *everything* over to the build directory, and all source copies are now kept in the source/ directory.
Fixed: Bound orientation change event to window, instead of body

Fixes #117
New mandatory setting parameter: imageRoot

This parameter corresponds to the image root directory set in the divaserve file.

Note: By default, this is relative to your root directory, so it's set to /something/somethingElse. However, you can set the FILESYSTEM_PREFIX for IIP to provide a new root. If you have set this, imageRoot should be relative to the directory you defined in FILESYSTEM_PREFIX. If your images are in /mnt/images/projectA/foo.jp2, and you have set FILESYSTEM_PREFIX to /mnt/images, you should set imageRoot to projectA; If you have not set FILESYSTEM_PREFIX, you should set it to /mnt/images/projectA.
New build 2.2.0
Fixed: Diva plugins weren't aware of the changes to imageRoot and imageDir.
New Bugfix build. This will be RELEASE 2.2.1
Formatting
New: Allow toolbar to be configured to draw in another parent

Previously the toolbar was hardcoded to draw in the diva wrapper element. This commit adds the ability to set the element where the toolbar will draw.
Fixed: Remove old diva-min.js from root
Fixed: Updated README to fix some outdated information
Updated minified build. This will be RELEASE-2.2.2
New: Callback for when the current page is set

This callback is executed later than onPageLoad, and is handy for triggering things that should happen when the document is fully in the viewer (onPageLoad gets triggered when the page is loaded, which may be outside of the viewport).
New: Callback for onDocumentLoaded

This callback is executed when the document has been loaded and is ready to go.
