phobosx.signal ready

I finished my std.signals2 implementation. I moved it to:

https://github.com/phobos-x/phobosx/blob/master/source/phobosx/signal.d

you can also find it in the dub registry:

http://code.dlang.org/packages/phobosx

Documentation:

https://vhios.dyndns.org/signal.html

I renamed it from std.signals2 to phobosx.signal. When included in
phobos it will most likely be named std.signal.

Improvements over std.signals:

- No more heisenbugs 
(http://d.puremagic.com/issues/show_bug.cgi?id=4150)

- safe connect method to an object's method (weak ref semantic)

- support for indirect connect to an object's method via a wrapper
   delegate (weak ref semantics to target object)

- strongConnect method for connecting to non objects. (strong ref
   semantics)

- disconnect method for disconnecting all methods of a given 
object with
   a single call.

- Proper exception handling. Meaning if a slot throws an 
exception the
   other slots will still be called and all slot exceptions are 
chained
   together.

- signal methods are safe to call from within a slot.

- signal copying is forbidden. While this implementation would not
   cause segfaults when copied like std.signals, it is not really 
clear
   how a signal should be copied in the general case.

- Signals are implemented as structs instead of a mixin and every
   template parameter agnostic code also does not depend on the 
template
   parameters -> avoid template bloat.

- Memory footprint for empty signal is even lower than the one of 
the
   current std.signals, which is important because many signals 
end up not
   being used at all.

- Provided string mixin which allows only the containing class to
   issue emit(), but everyone to connect.

- Slots are called in the same sequence as they were registered.

I could not find any more bugs, so please use it and show me the 
bugs I missed :-)

Have fun!
