phobosx.signal ready

Ok, I came around to test it, finally.


A few things:
 * I don't like the separation between connect/strongConnect
 * I would like to bind a strongConnect to a class, if the class is gone
the strongConnect should be gone, too. E.g.
"window.single_key_down[JUMP].strongConnect({ physics.jump(); });"
physics is a class variable, this will blow up once the class holding it
is gone
 * I don't like the connect api for class-method connects, I write all
the time "window.on_mouse_pos.connect!"on_mouse_pos"(this);" (the this
is kinda annoying), doesn't something like signal.connect!(bla)() work,
with an alias template param?
 * Why is there no convenience class for Signal? Since the copy
constructor is disabled, I have to use a pointer, not a big deal, but a
class would be more convenient.


Other than that! Great job, I had not a single segfault so far (only 3
"starts" so far though :>)
