Allow giving tips to users on the site, and not only tip jars
In addition to giving tips to projects, I want to give tips for actual Propster users. For example, if they start a tip jar for a really good cause, I want to tip them. Alternatively, a person may not have any particular project, but wants to accept tips. The tip jar will have no info about the project, but only about the person. The person will have a Propster account, so by default, it will be verified.
