Normalize all signal connections

[valerio]

When we have a method like this: method( const type1 &arg1, const type2 arg2, type3 *arg3, type4 arg4 )

and we need to connect() it, instead of the full type-only form:
method(const type1&,const type2,type3*,type4)
we can just use the normalized version of it:
method(type1,type2,type3*,type4)

This way,

connect( object, SIGNAL(   call(const type1&,const type2,type3*,type4) ),
         this,   SLOT  ( method(const type1&,const type2,type3*,type4) ) );

becomes

connect( object, SIGNAL(   call(type1,type2,type3*,type4) ),
         this,   SLOT  ( method(type1,type2,type3*,type4) ) );

I'm sure the difference is obvious - a lot less line length issues, specially when we consider that aligning the code to adhere to the coding style makes for 130+ columns wide lines of code. :P
