Fixed issues with add_fd() addon. Dialogs popped up, especially from

service_watcher() would not be drawn correctly yielding program hang since
add_fd() would not send events to fltk.

Also commented hack from Splash to keep it's window at the top of all;
now, using add_fd() evoke will get events before fltk which is what I want.
Not tested with other wm's.

Note: enabling that hack will surely crash evoke unless fl_handle() is removed
from main evoke loop.
