From 3e217ba90914c1100228f7f54af3f4763967b9b9 Mon Sep 17 00:00:00 2001
From: david <david>

Subject: [PATCH] Instead of reading $FG_ROOT/gui.xml, recursively read all
 files under the $FG_ROOT/gui/ directory; that way, each dialog can have a
 separate configuration file, and management should be simpler.
