[Vala] new signal syntax

[Adam Dingle <adam yorba org>]

I, for one, would like to express my preference for the old signal 
syntax (+= and -=) over the new syntax (connect and disconnect).  I 
prefer the old syntax because

1) I find it more readable, especially when a lambda expression is involved.

2) Signals are special: they are part of the language and so I prefer 
them to be expressed using language syntax rather than what looks like a 
method call (and which is, I'll grant, likely just a method call behind 
the scenes).  I'm often interested in scanning through code visually to 
find which signal handlers are set; this is much easier with the += syntax.

In the bug regarding this change 
(http://bugzilla.gnome.org/show_bug.cgi?id=566847) it was stated that += 
doesn't seem appropriate for a signal, but I don't think it's really any 
stranger than, say, using + to concatenate strings even though the 
operator was originally conceived for numeric addition.

In almost every other way I'm very happy with Vala and the direction of 
its development.  Keep up the great work!
