Multiple donation projects

[Norwayman]

I for sure would have loved the option of making varios donation projects where the clients/users can donate to what cause they find best.

Also, I would have loved the opportunity to make all the donation projects available on ONE page
so that it would be easy for a client/user to get an overview and then choose the project he/she would like to support.

This is interesting, and upon a simple thought process it may not be that crazy of a thing to add. For now I'm going to tag this for down the road, at least until I do some testing.

I agree, interesting to add and also related to #36

Campaigns will solve this feature, and will also solve #36.

The two commits above are just ground work, mostly closing up #36 after some testing.
