Clearspring Piwik widgets export fails with message: "Thanks for trying Launchpad On-Page. Unfortunately, your user ID is invalid. Please check it and try again."

To reproduce, go to the piwik demo, select a widget, and click on export anywhere.

We contacted clearspring a while ago but no answer see forum post

We have a few possible solutions:
1 - remove this feature from Piwik

2 - find another provider like clearspring providing similar API

3 - contact clearpspring and ask them again why this is happening, and if we can somehow secure a user id

4 - ask users to provide their own clearspring user ID in order to use the feature

If we can't do 3- or 4- quickly we should just do 1- and remove clearspring feature from Piwik.

(In [2010]) Fixes #861

Removed clearspring support. It only worked well for a few months before they eventually banned us or something... Probably not a good idea to have Piwik relying on a 3rd party tool anyway.
