Recent donations and projects sidebar is empty

[ggorlen]

The recent donations and projects sidebar is empty, giving the page a broken or half-finished look.

There is an old commit that removed what I recall being a working recent donations/projects listing: c3e6013. It may no longer work. I opened a PR uncommenting the query to populate the template in #41 but wasn't sure if this was an appropriate or functional fix so I'm moving it to this issue.

Suggested resolutions:

• If the feature is working, re-open above PR and merge (or whatever else might be needed to fix).
• If the feature is non-working, temporarily or permanently, we should remove the sidebar to avoid the page from appearing broken or partially functional.
