+Subject: [PATCH] Modifies quit to handle restarts and adds SIGHUP and SIGTERM
+ handlers.
+
+Modified quit() to restart if it receives arg .i = 1
+MOD+CTRL+SHIFT+Q was added to confid.def.h to do just that.
+
+Signal handlers were handled for SIGHUP and SIGTERM.
+If dwm receives these signals it calls quit() with
+arg .i = to 1 or 0, respectively.
+
+To restart dwm:
+MOD+CTRL+SHIFT+Q
+or
+kill -HUP dwmpid
+
+To quit dwm cleanly:
+MOD+SHIFT+Q
+or
+kill -TERM dwmpid
