I would like to drop support for Qt 4 on the default branch.

I would also be fine with requiring Qt 5.6 or newer. Qt 5.6 is the
oldest LTS still supported by Qt (end-of-life is March 2019 actually),
it was released in March 2016. But some Ubuntu users may want us to keep
supporting Qt 5.5 if possible.

IMHO, as far as implementation, I think we should *not* have configure
do a hard version check, but we could have a feature test that requires
the newest feature that we actually use (like QStandardPaths), and
delete all older feature tests and conditionals.
