Thanks for noticing!

Fixed. The fix for it was quick and simple:

-                   if (m/(0x[\dA-Fa-f]+)[\s\,]+(KEY_[^\s\,\}]+)/) {
-                           $out .= "$1 $2\n";
+                 if (m/(0x[\dA-Fa-f]+)[\s\,]+(KEY|BTN)(\_[^\s\,\}]+)/) {
+                         $out .= "$1 $2$3\n";

Basically, the regex there weren't expecting mouse buttons. Some MCE remotes
have it.

I also updated the keytables, syncing it with the very latest git tree.
