Added a link to the lein-cucumber project (closes #16).
Added a link to the UN project (closes #15).
Added a link to the libcpr project.
Added an unintrusive Bitcoin donation link to the site footer.

Any received donations will go toward the upkeep of the Unlicense
initiative, at the moment consisting chiefly of domain registration
and hosting costs at Namecheap and DreamHost, respectively.

I wouldn't mind fully securing the Unlicense.org domain registration
by prepaying for a decade or two of annual domain costs. You can
now help make that happen on your part.
