Substantial refactoring + bug fixes

New Features:

* No installation required - it works out of the box
* Easy to use
* Drag and drop files and folders
* Large uploads
* Multiple uploads
* Downloads
* No legacy issues - it works on IE6 and every major browser
* No flash or java required

If you're putting this on a public web server, make sure you secure your
install so it cannot be accessed by others.

Bugfixes:

Autodetect installed directory
Autodetect a directory of files to manage
Fixed file detection to not throw PHP notices if the file array is empty
Now given the proper mouse pointer over the "back" button
Introduced a better debug feature that all debugging will be routed
through
adding the ability to delete files back into the software - it was just
missing from the UI

//todo: there will be bugs when dealing with files that have the same
name as a directory
