Clippings version 1.0.6.18.2001

summary 
- - - - -
script handles all Clipping functionality
this is a stripped down version of the IHT Clippings code
the primary difference is the removal of animation code which I am not that happy with
and a few minor improvements

+  Add to Clippings
+  Link to Clipping
+  Update Clipping as read
+  Remove Clipping(s)
+  Save Clippings

comments
- - - - - - 
Clippings only work with DOM browsers.  Opera at this point does not have enough of the DOM to support clippings.
There is little or no feature/browser compatibiliy checking in this code, so use wisely.
The code has been tested on IE 5.0, 5.5, 6.0 on Windows, IE 5.0 on Mac, and various versions of Netscape 6.0 and Mozilla.

loadClippingURL() will control how Clipping urls are handled.  You will want to customize this method.
clippingsTag is a variable which defines what tag your Clippings icon will be nested in.  All clipping icons must be in the same type of tag.

there is a fix for a display error in Mozilla on lines 266-268 and again on
