it can be confusing when projects have no downloads yet (the default) and when projects use both svn and git (with git only for the website).
So to avoid bad links, lets disable the links to source/downloads.
The actual website of the projects can include links to source/downloads as the projects see fit.
Maybe we only show those source links on the forge page if its a private project? As its handy when stuff starts up, before a site is created
