FvwmTaskBar Maildir patch

[Jim C. Brown]

This patch, which applies to fvwm 2.5.10, gives FvwmTaskBar the ability to
read from a qemu Maildir mail box. It needs some work (may not be a compliant
Maildir reader) but it seems to work.

I don't feel confortable playing around with the Makefiles so I just added
#define USE_MAILDIR at the top of Goodies.c (I'm hoping that someone who
knows more can do this right).
