Add copy-to-clipboard element for upload/download lists.

The title text currently cannot be internationalized, because I wanted to keep the initialization out of the Toadlets.

Feature-wise this is nice, the implementation could use some additional care.

The title text currently cannot be internationalized, because I wanted to keep the initialization out of the Toadlets.

That can totally be worked around by putting the translated texts into an invisbile <div> somewhere on the page, and letting the javascript read the <div>s. 🙂

@bertm @Bombe Thank you for your review (despite the not so great shape of the code)!

I addressed all comments now:

• The script only runs once, regardless of how often it is included
• The icon is now the inline SVG by bertm
• the title is from the toadlet and localizable (via dataset.copytitle).
• it can’t be selected and the cursor is set as pointer

I left out the spacing adjustments because they were not needed with the SVG.

The SVG is added via innerHTML, but as static data, so it does not pose a risk (no escaping necessary).

Can you give this another look?
