Change resourceUri to a text input

When using longer resource links, the resourceUri <code> block flows
outside of the runner div and lays over the top of the docs. I’ve
changed the resourceUri to be a text input, monospace formatted, with a
select() onclick to make it easier to read the URL, and really simple
to select it and run it in a browser.

Exception for QoQ with blank column name

There are instances where a column name from a QoQ could return an
empty string as a column name, causing an exception when trying to
reference that column name when converting a query to an array. This
change will ensure that we have a valid column name before attempting
to reference it.
