Revert "Make the full text fit in the UI buttons."

This reverts commit ffe79fa1ad957fe34005de4fc60b2072b1acd43c.

Apparently that css controls more than the downlaod buttons.  This
change looks ugly on the main control page and potentially others.  I
know if I don't revert this now, I'll be called out on it (for good
reason) soon!
