Combine additional jquery/plugin files into one
Remove single file references
Moved dragdrop.js to serendipity_Editor.js.
Please test. Might make trouble in the installer/upgrader?
This build includes only the tests and shivs in Modernizr we do
actually use. If we add tests (in CSS or JS) or find some are
missing, this build needs to be renewed.

Includes adapting the layout to match the installer, using a proper
element for removeFiles msgs, removing unnecessary msg_* wrappers,
fixing the upgrader buttons etc.
This includes only the icons actually used or intended to be used
in the backend. Please note that unfortunately, some class names
have changed. Also some icons have been exchanged.
