🦊 fix firefox drag n drop issues

fix #16

When drag'n dropping into firefox, firefox, on the first drag'n drop creates a window which when resized by umberwm, sometimes makes firefox crash.

This makes sure this window is ignored by identifying it with

wm_class == ["firefox", "firefox"] ("normal" windows are called ["Navigator", "firefox"])
WM_NORMAL_HINTS { max_height, max_width } both == 0 ("normal" windows have 16384)

Also, ignore alltogether _NET_WM_WINDOW_TYPE_DND

Hmm. Seems unfortunate to have code so specifically targeted at firefox, but I can't think of a way to make it more general. Looks good to me.
