Make the donation button easier to find, folks

I have just spent a good 10minutes trying to find the donation button on - that’s not what you should expect from someone stopping by to drop a little something like me.
I know the button is always shown in my installation after updating, but to find it on really is a challenge.

for those who may not have found it either, it’s here:

When donating, the paypal header says “support PIWIK 2.0 development”, you might want to review that some time as well :slight_smile:

Thanks for delivering, folks,
and best wishes from a happy piwik user
