use JS to "detect" browser-JS-capability

[blueyed@…]

This is the fckeditor.php file as I've also sent it to Frederico.

It obsoletes the isCompatible() method and uses javascript itself to "detect" if it is compatible. Simply by using document.write().

It also detects/converts the Width and Height members better to html attribute values.

It was based on 2.1.
