gui/clone-uniform
=================
Bind to a key (the example config uses :kbd:`Ctrl`:kbd:`C`), and activate in the Uniforms
page of the military screen with the cursor in the leftmost list.

When invoked, the script duplicates the currently selected uniform template,
and selects the newly created copy.
