"Put link in clipboard" does not work with Linux

I had to learn that Opera just does not support this :-( and for Firefox you have to allow this explicitely. Therefore I've written to small patches: One to alert Firefox users when and how they must enable copying to clipboard.

The other one warns Opera users that the clipboard is not supported but to give them a similar functionality, the patch replaces the address of file nodes by their link. I.e., I changed

this.clickObj.setAttribute('href', '#' );

to

 this.clickObj.setAttribute('href', getBaseUrl() + "\/webfm_send\/" + fileObj.id );

if the browser is Opera and the file is in the database. Thus, Opera users can right-click on the file name in either the attachment list or the filetree (since they don't get the webfm context menu, see http://drupal.org/node/246918) and copy the files adress to the clipboard by Opera "Copy link address".

I'm not sure if you like that because I don't know if changing the file nodes address changes something else. Drag&drop etc. all still seemed to work, but you will know better :-)

If this patch doesn't destroy anything else, maybe it could be used as clipboard replacement for Opera users.

Sorry, double post :-)
